Can You Upgrade Windows 7 To Windows 11 For Free

Original equipment manufacturers can still ship computers without a TPM 2.0 coprocessor upon Microsoft's approval. Some third-party software may refuse to run on unsupported configurations of Windows 11. If you have a computer running Windows 7, it is possible to upgrade to Windows 11 without losing your files using the ISO file, but the process will require a complete reinstallation. This means that your apps and settings won't carry over to the new installation. However, before you upgrade to Windows 11 from Windows 7, you will still need to make sure the laptop or desktop meets the minimum system requirements. For example, the device must include a motherboard with UEFI firmware, and the processor must be an Intel's 8th Gen or newer or an AMD Zen 2 or newer.

From what it looks like, Windows users have three options to upgrade to the upcoming version of the operating system. They can either upgrade, clean install a new version or reimage their devices. As part of the minimum system requirements, Windows 11 only runs on devices with a Trusted Platform Module 2.0 security coprocessor.

can you upgrade windows 7 to windows 11 for free - This is in addition to the requirements of TPM 2

According to Microsoft, the TPM 2.0 coprocessor is a "critical building block" for protection against firmware and hardware attacks. In addition, Microsoft now requires devices with Windows 11 to include virtualization-based security , hypervisor-protected code integrity , and Secure Boot built-in and enabled by default. The operating system also features hardware-enforced stack protection for supported Intel and AMD processors for protection against zero-day exploits. Internet Explorer has been replaced by the Chromium-based Microsoft Edge as the default web browser, and Microsoft Teams is integrated into the Windows shell.

AsPanos Panay shared in June, this is the first version of a new era of Windows. And, for customers who are using a device that is not eligible for Windows 11, Windows 10 is a great place to be. Windows 10 will be serviced through Oct. 14, 2025and we previously announced that the next feature update to Windows 10 is coming very soon, continuing to offer you both support and choice with Windows. This will not erase any of your personal files and is similar to an OTA (over-the-air) update – however, it's always advisable to have backups. Similarly, you can create a bootable USB drive or a disk image to perform a clean install.

can you upgrade windows 7 to windows 11 for free - Once the upgrade rollout has started

If you have had the same installation for a long time, you might need to analyze and repair the current setup to fix missing or damaged files. Otherwise, during the upgrade process, the chances of running into issues will be high. However, if you plan to proceed with a clean installation using a bootable USB flash drive, then you can't skip this suggestion since the previous installation will be erased during the process. "Most devices available for purchase now will be upgradeable to Windows 11. You will have the option to upgrade, clean install, or reimage Windows 10 devices to move to Windows 11. For Windows 7 devices that meet hardware requirements, you will need to clean install or reimage to go directly to Windows 11," the guide on Lenovo's website reads.

can you upgrade windows 7 to windows 11 for free - Similar to how end users are notified when updates are available in Windows 10

Our launch approach to Windows 11 leverages the well-established systems and processes used for the 1.3 billion Windows 10 devices we have shipped and serviced for over five years. We will use a measured and phased process in offering Windows 11 as we have done with Windows 10 feature updates. Our objective is to provide you with a smooth upgrade experience. We will begin to offer the upgrade to eligible new devices first1,2. Then, as with previous rollouts, we will study device health data and other signals to determine the pace at which Windows 11 is offered via Windows Update. Microsoft is soon going to launch its new Windows 11 and if you are a Windows 10 user, an upgrade to the new operating system would be free.

can you upgrade windows 7 to windows 11 for free - More information on how that is presented will be available at a later date

The official release date is not out yet, but Windows 11 is expected to arrive in the 2021 holiday season, sometime in the coming months. As soon as it arrives, users will be able to update to the new operating system just like how it was done with Windows 10. As long as your desktop or laptop meets the minimum requirements. Devices that do not meet the minimum system requirements will remain on Windows 10 and continue to be supported with security updates. Customers using long term service releases will continue to be supported through the published end of support dates.

can you upgrade windows 7 to windows 11 for free - Additional desktop notification options may be also be added at a later date

For more information about Windows 10 support, see HP products tested with Windows 10. Microsoft doesn't recommend installing Windows 11 on devices that don't meet the system requirements, but you'll still be able to do so. It's worth noting that you might not get Windows 11 updates on PCs with unsupported processors. Besides chaining upgrades, it may also be possible to clean install Windows 11 on a device instead. Downside to this is that all installed programs, customizations and files on the main drive, won't be available after the installation completes.

You need to create backups of these files, and install programs anew. Many games that use Anti-cheat tools also have started relying on Windows 11 security features to provide fair gameplay. While these games still work on Windows 10, it is only a matter of time before Windows 11 ends up becoming a requirement. Microsoft makes you accept that the company can stop providing updates, and security patches to Windows 11 on these devices. While Microsoft is unlikely to do that in practice, it's still better to be on the safer side.

Also, you're likely to run into driver incompatibility issues on unsupported devices. Especially, if your computer is running hardware that is more than 5-6 years old. At least 16GB of RAM The basic system requirements of Windows 11 differ significantly from Windows 10. Windows 11 only supports 64-bit systems such as those using an x86-64 or ARM64 processor; IA-32 processors are no longer supported. Thus, Windows 11 is the first ever consumer version of Windows not to support 32-bit processors and 16-bit software . The minimum RAM and storage requirements were also increased; Windows 11 now requires at least 4GB of RAM and 64GB of storage.

can you upgrade windows 7 to windows 11 for free - Citing security considerations

S mode is only supported for the Home edition of Windows 11. The compatibility list includes the Intel Core i7-7820HQ, a seventh-generation processor used by the Surface Studio 2, although only on devices that shipped with DCH-based drivers. For example, even though Windows 11 is available as a free optional update for Windows 10, the device must meet the new system requirements. You need to ensure that the Trusted Platform Module and Secure Boot are enabled on the computer.

You also need to make sure the device has enough space and there are no problems before continuing with the upgrade. Furthermore, you want to create a backup in the case you need to roll back, check the activation status, and create installation media. Microsoft offers several ways to download Windows 11 manually.

can you upgrade windows 7 to windows 11 for free - Windows 11 also drops support for 32-bit x86 CPUs and devices which use BIOS firmware

One is to use the Installation Assistant app, which you install on your PC to trigger a normal upgrade install via Windows Update. The second is to use the Windows 11 Media Creation Tool, which automates the process of creating a bootable USB install drive or downloading an install ISO file. Once you have a USB drive, you can either boot from it to perform a clean install or run the Setup app from within Windows 10 to do a normal upgrade install. You can also burn the ISO to a DVD, but installing from any USB drive, even an old USB 2.0 drive, will be much faster, so you shouldn't do that. Finally, you can just download an ISO file directly from Microsoft's site. Microsoft has limited the number of devices that can officially run the latest version of Windows, with its restrictive hardware requirements.

can you upgrade windows 7 to windows 11 for free - The official

Most of the latest laptops will support Windows 11, but you're probably out of luck if you built your own desktop PC or use anything more than around four years old. With that said, if your device supports Windows 11, there is no reason you should not upgrade. After the announcement of the launch of Windows 11, there was a lot of fuss about the devices that could support it. Windows 11 officially requires a Trusted Platform Module 2.0, UEFI, and Secure Boot in order to run on a machine, and if yours doesn't meet those requirements, you will not be able to install it. The easiest way to check whether your hardware is eligible is by installing Microsoft's own PC Health Check application. You can refer to our knowledge base for a list of tested systems to determine if your device eligible to upgrade to Windows -11.

can you upgrade windows 7 to windows 11 for free - However

Many PCs that are less than four years old will be able to upgrade to Windows 11. They must be running 20H1 or later version of Windows 10 and meet the minimum hardware requirements to receive the Windows 11 upgrade. It's not imperative that you upgrade your system to Windows in the next couple of weeks, or even months.

can you upgrade windows 7 to windows 11 for free - Some users will be offered the option to upgrade in their Settings menu on or around the October 5th official launch date while others may be waiting until 2022

For many people, that's about the time to upgrade to a newer device, one that will come with Windows 11 already installed. In October 2019, Microsoft announced "Windows 10X", a future edition of Windows 10 designed exclusively for dual-touchscreen devices such as the then-upcoming Surface Neo. Legacy Windows applications would also be required to run in "containers" to ensure performance and power optimization. Microsoft stated that it planned to release Windows 10X devices by the end of 2020. Once you complete the steps, the tool will download the files and create an installation media, which you can then use to upgrade a compatible computer to Windows 11.

can you upgrade windows 7 to windows 11 for free - According to an FAQ page recently published by Lenovo

There is a way to install Windows 11 on unsupported hardware, but we wouldn't recommend it. Although Microsoft hasn't confirmed it, the company has heavily implied that unsupported users won't receive critical security updates. If you still want to install, you can do so using the Media Creation Tool, which bypasses hardware checks. If you're using Windows 10, installing Windows 11 will feel just like installing a Windows 10 feature update. Microsoft has said exactly that, which means the upgrade process should be pretty easy. It's also been confirmed that Windows 11 will be a free update for Windows 10 users, as long as their PC is compatible.

The free upgrade will start rolling out this holiday and it has no set end date yet, so you should be able to upgrade whenever you feel ready. Click Next to have Windows 11 check for any updates, then accept the license terms. The Ready to install screen shows that Windows 11 will be installed and that your personal files and apps will be kept. You can then elect to keep personal files and apps, personal files only, or nothing.

can you upgrade windows 7 to windows 11 for free - From what it looks like

With the Insider build being tested by many users, it's only a matter of time before Microsoft details the release schedule for Windows 11 and what the upgrade eligibility will be. However, with Lenovo seemingly jumping the gun on this, it may alleviate some users' worries if their PC is eligible, as long as they meet the minimum requirements. From what Lenovo has explained, you can update from Windows 7 and 8 to Windows 11 free of charge, but only with a clean install or a reinstall on your PC. This may frustrate some, but if you have more than one hard drive installed, with one solely for Windows, it may not be much of a frustration. However, if you store everything on a single storage device, it may be a long weekend ahead of installing Windows 11, and restoring your data.

can you upgrade windows 7 to windows 11 for free - They can either upgrade

Even though Windows 11 can work on most unsupported PC, this doesn't mean it will work perfectly. Depending on the PC, some of the features may not work correctly, or Windows may corrupt or malfunction. Microsoft also doesn't recommend installing Windows 11 on unsupported devices, and there is no guarantee such devices will receive all future updates. Microsoft has also provided an option to create a bootable USB drive or DVD from its Windows 11 software page.

can you upgrade windows 7 to windows 11 for free - As part of the minimum system requirements

Can I Upgrade Windows 7 To Windows 11 For Free Additionally, you can create a Windows 11 Disk Image that will be available on a bootable installation media such as a USB flash drive or DVD to help you install the new Windows version on your machine. Next, Microsoft says it will look at hardware eligibility, reliability metrics and other factors on existing Windows 10 devices to determine when to offer the latest OS through Windows Update. It's a similar approach to how the company has handled Windows 10 feature updates over the years. You can find out whether your device is compatible using the PC Health Check app.

Can I Upgrade Windows 7 To Windows 11 For Free

Another option is to create installation media on a USB key and install the operating system using that. A final option is to download a Windows 11 disk image to create a bootable installation media such as a USB stick or DVD, or create a virtual machine to install the new Windows software. There are many users who, after the release of Windows 11, went ahead and checked whether their PC is eligible to be upgraded with Windows 11. Sadly, they found out that their PC does not meet the minimum requirements to install Windows 11.

How To Use Two Columns In Group By

We can group the resultset in SQL on multiple column values. All the column values defined as grouping criteria should match with other records column values to group them to a single record. Let us use the aggregate functions in the group by clause with multiple columns. This means given for the expert named Payal, two different records will be retrieved as there are two different values for session count in the table educba_learning that are 750 and 950. Grouping on multiple columns is most often used for generating queries for reports, dashboarding, etc.

how to use two columns in group by - We can group the resultset in SQL on multiple column values

Group by is done for clubbing together the records that have the same values for the criteria that are defined for grouping. When a single column is considered for grouping then the records containing the same value for that column on which criteria are defined are grouped into a single record for the resultset. There's an additional way to run aggregation over a table. If a query contains table columns only inside aggregate functions, the GROUP BY clause can be omitted, and aggregation by an empty set of keys is assumed. The SQL GROUP BY Statement The GROUP BY statement groups rows that have the same values into summary rows, like "find the number of customers in each country".

The GROUP BY statement is often used with aggregate functions to group the result-set by one or more columns. A complete guide on sql function sum with find total on multiple columns, sum group by, sum of two columns, where clause, average of sum, aggregate functions. NET Database SQL MySQL PostgreSQL SQLite NoSQL SQL SUM() function with group by The aggregate functions summarize the table data. The aggregate functions are applied in order to return just one value per group. All the expressions in the SELECT, HAVING, and ORDER BY clauses must be calculated based on key expressions or on aggregate functions over non-key expressions . In other words, each column selected from the table must be used either in a key expression or inside an aggregate function, but not both.

how to use two columns in group by - Let us use the aggregate functions in the group by clause with multiple columns

The SQL GROUP BY Clause is used to output a row across specified column values. It is typically used in conjunction with aggregate functions such as SUM or Count to summarize values. Rather than returning every row in a table, when values are grouped, only the unique combinations are returned. This syntax allows users to perform analysis that requires aggregation on multiple sets of columns in a single query. Complex grouping operations do not support grouping on expressions composed of input columns. If the WITH TOTALS modifier is specified, another row will be calculated.

how to use two columns in group by - This means given for the expert named Payal

This row will have key columns containing default values , and columns of aggregate functions with the values calculated across all the rows (the "total" values). SQL SUM() function with group by SUM is used with a GROUP BY clause. Once the rows are divided into groups, the aggregate functions are applied in order to return just one value per group.

how to use two columns in group by - Grouping on multiple columns is most often used for generating queries for reports

Pandas comes with a whole host of sql-like aggregation functions you can apply when grouping on one or more columns. This is Python's closest equivalent to dplyr's group_by + summarise logic. Here's a quick example of how to group on one or multiple columns and summarise data with aggregation functions using Pandas. It filters non-aggregated rows before the rows are grouped together. To filter grouped rows based on aggregate values, use the HAVING clause.

how to use two columns in group by - Group by is done for clubbing together the records that have the same values for the criteria that are defined for grouping

The HAVING clause takes any expression and evaluates it as a boolean, just like the WHERE clause. As with the select expression, if you reference non-grouped columns in the HAVINGclause, the behavior is undefined. The GROUP BY clause is often used with aggregate functions such as AVG(), COUNT(), MAX(), MIN() and SUM().

how to use two columns in group by - When a single column is considered for grouping then the records containing the same value for that column on which criteria are defined are grouped into a single record for the resultset

In this case, the aggregate function returns the summary information per group. For example, given groups of products in several categories, the AVG() function returns the average price of products in each category. The GROUP BY clause is used in a SELECT statement to group rows into a set of summary rows by values of columns or expressions. First, you specify a column name or an expression on which to sort the result set of the query. If you specify multiple columns, the result set is sorted by the first column and then that sorted result set is sorted by the second column, and so on. To be perfectly honest, whenever I have to use Group By in a query, I'm tempted to return back to raw SQL.

how to use two columns in group by - Theres an additional way to run aggregation over a table

I find the SQL syntax terser, and more readable than the LINQ syntax with having to explicitly define the groupings. In an example like those above, it's not too bad keeping everything in the query straight. However, once I start to add in more complex features, like table joins, ordering, a bunch of conditionals, and maybe even a few other things, I typically find SQL easier to reason about. Once I get to the point where I'm using LINQ to group by multiple columns, my instinct is to back out of LINQ altogether. However, I recognize that this is just my personal opinion.

how to use two columns in group by - If a query contains table columns only inside aggregate functions

If you're struggling with grouping by multiple columns, just remember that you need to group by an anonymous object. If you've used ASP.NET MVC for any amount of time, you've already encountered LINQ in the form of Entity Framework. EF uses LINQ syntax when you send queries to the database. While most of the basic database calls in Entity Framework are straightforward, there are some parts of LINQ syntax that are more confusing, like LINQ Group By multiple columns.

how to use two columns in group by - The SQL GROUP BY Statement The GROUP BY statement groups rows that have the same values into summary rows

The GROUP BY clause is used in conjunction with the aggregate functions to group the result-set by one or more columns. The GROUP BY statement is often used with aggregate functions ( COUNT() , MAX() , MIN() , SUM() , AVG() ) to group the result-set by one or more columns. The GROUP BY clause divides the rows returned from the SELECTstatement into groups.

how to use two columns in group by - The GROUP BY statement is often used with aggregate functions to group the result-set by one or more columns

For each group, you can apply an aggregate function e.g.,SUM() to calculate the sum of items or COUNT()to get the number of items in the groups. When you use a GROUP BY clause, you will get a single result row for each group of rows that have the same value for the expression given in GROUP BY. Instructions for aggregation are provided in the form of a python dictionary or list. The dictionary keys are used to specify the columns upon which you'd like to perform operations, and the dictionary values to specify the function to run.

how to use two columns in group by - A complete guide on sql function sum with find total on multiple columns

The aggregation can be performed more effectively, if a table is sorted by some key, and GROUP BY expression contains at least prefix of sorting key or injective functions. In this case when a new key is read from table, the in-between result of aggregation can be finalized and sent to client. This behaviour is switched on by the optimize_aggregation_in_order setting. Such optimization reduces memory usage during aggregation, but in some cases may slow down the query execution.

how to use two columns in group by - NET Database SQL MySQL PostgreSQL SQLite NoSQL SQL SUM function with group by The aggregate functions summarize the table data

WITH CUBE modifier is used to calculate subtotals for every combination of the key expressions in the GROUP BY list. WITH ROLLUP modifier is used to calculate subtotals for the key expressions, based on their order in the GROUP BY list. Even though the database creates the index for the primary key automatically, there is still room for manual refinements if the key consists of multiple columns.

how to use two columns in group by - The aggregate functions are applied in order to return just one value per group

In that case the database creates an index on all primary key columns—a so-called concatenated index (also known as multi-column, composite or combined index). Note that the column order of a concatenated index has great impact on its usability so it must be chosen carefully. The SQL COUNT () function returns the number of rows in a table satisfying the criteria specified in the WHERE clause. SUM() function with group by​​ It is better to identify each summary row by including the GROUP BY clause in the query resulst.

how to use two columns in group by - All the expressions in the SELECT

All columns other than those listed in the GROUP BY clause must have an aggregate function applied to them. When you use the SELECT statement to query data from a table, the order of rows in the result set is not guaranteed. It means that SQL Server can return a result set with an unspecified order of rows. If you want to break your output into smaller groups, if you specify multiple column names or expressions in the GROUP BY clause. Output in each group must satisfy a specific combination of the expressions listed in the GROUP BY clause. The more columns or expressions entered in the GROUP BY clause, the smaller the groups will be.

how to use two columns in group by - In other words

We can observe that for the expert named Payal two records are fetched with session count as 1500 and 950 respectively. Note that the aggregate functions are used mostly for numeric valued columns when group by clause is used. Criteriacolumn1 , criteriacolumn2,…,criteriacolumnj – These are the columns that will be considered as the criteria to create the groups in the MYSQL query.

how to use two columns in group by - The SQL GROUP BY Clause is used to output a row across specified column values

There can be single or multiple column names on which the criteria need to be applied. SQL does not allow using the alias as the grouping criteria in the GROUP BY clause. Note that multiple criteria of grouping should be mentioned in a comma-separated format. Aggregate_function – These are the aggregate functions defined on the columns of target_table that needs to be retrieved from the SELECT query. You can use any of the grouping functions in your select expression. Their values will be calculated based on all the rows that have been grouped together for each result row.

how to use two columns in group by - It is typically used in conjunction with aggregate functions such as SUM or Count to summarize values

If you select a non-grouped column or a value computed from a non-grouped column, it is undefined which row the returned value is taken from. This is not permitted if the ONLY_FULL_GROUP_BY SQL_MODE is used. When multiple statistics are calculated on columns, the resulting dataframe will have a multi-index set on the column axis. The multi-index can be difficult to work with, and I typically have to rename columns after a groupby operation. The output from a groupby and aggregation operation varies between Pandas Series and Pandas Dataframes, which can be confusing for new users. As a rule of thumb, if you calculate more than one column of results, your result will be a Dataframe.

how to use two columns in group by - Rather than returning every row in a table

For a single column of results, the agg function, by default, will produce a Series. In the subtotals rows the values of already "grouped" key expressions are set to 0 or empty line. Here, the grouped result data is sorted by the Total Earning of each group in descending order in mysql group by multiple columns. The HAVING clause with SQL COUNT () function can be used to set a condition with the select statement. The HAVING clause is used instead of WHERE clause with SQL COUNT () function.

how to use two columns in group by - This syntax allows users to perform analysis that requires aggregation on multiple sets of columns in a single query

The GROUP BY with HAVING clause retrieves the result for a specific group of a column, which matches the condition specified in the HAVING clause. SUM of Multiple columns of MySQL table Now we will learn how to get the query for sum in multiple columns and for each record of a table. 3 and then divide that from the total and multiply with 100 here is the query. SQL Server allows you to sort the result set based on the ordinal positions of columns that appear in the select list. It is possible to sort the result set by a column that does not appear on the select list.

how to use two columns in group by - Complex grouping operations do not support grouping on expressions composed of input columns

For example, the following statement sorts the customer by the state even though the state column does not appear on the select list. It's simple to extend this to work with multiple grouping variables. Say you want to summarise player age by team AND position.

how to use two columns in group by - If the WITH TOTALS modifier is specified

You can do this by passing a list of column names to groupby instead of a single string value. Often you may want to group and aggregate by multiple columns of a pandas DataFrame. Fortunately this is easy to do using the pandas.groupby()and.agg()functions. In this tutorial, you have learned you how to use the PostgreSQL GROUP BY clause to divide rows into groups and apply an aggregate function to each group. You can use the GROUP BYclause without applying an aggregate function.

how to use two columns in group by - This row will have key columns containing default values

The following query gets data from the payment table and groups the result by customer id. In this power bi tutorial, we learned power bi sum group by multiple columns. And also we discussed the below points power bi sum group by two columns using power query. You can query data from multiple tables using the INNER JOIN clause, then use the GROUP BY clause to group rows into a set of summary rows. For each group, you can apply an aggregate function such as MIN, MAX, SUM, COUNT, or AVG to provide more information about each group. In this tutorial, we have shown you how to use the GROUP BY clause to summarize rows into groups and apply the aggregate function to each group.

how to use two columns in group by - SQL SUM function with group by SUM is used with a GROUP BY clause

Can We Use Two Columns In Group By Pandas groupby is a powerful function that groups distinct sets within selected columns and aggregates metrics from other columns accordingly. Remember that you can pass in custom and lambda functions to your list of aggregated calculations, and each will be passed the values from the column in your grouped data. In the subtotals rows the values of all "grouped" key expressions are set to 0 or empty line.

Can We Use Two Columns In Group By

The only difference is that the result set returns by MySQL query using GROUP BY clause is sorted and in contrast, the result set return by MySQL query using DISTICT clause is not sorted. With the next row value Take the nth row from each group if n is an int, or a subset of rows if n is a list of ints. In SQL Server we can find the maximum or minimum value from different columns of the same data type using different methods. As we can see the first solution in our article is the best in performance and it also has relatively compact code. Please consider these evaluations and comparisons are estimates, the performance you will see depends on table structure, indexes on columns, etc.

how to use two columns in group by - Pandas comes with a whole host of sql-like aggregation functions you can apply when grouping on one or more columns

In this tutorial, you have learned how to use the SQL Server ORDER BY clause to sort a result set by columns in ascending or descending order. First, select the columns that you want to group e.g., column1 and column2, and column that you want to apply an aggregate function . The GROUP BY clause is an optional clause of the SELECT statement. The GROUP BY clause a selected group of rows into summary rows by values of one or more columns. In the following examples, df.index // 5 returns a binary array which is used to determine what gets selected for the groupby operation. Once the GroupBy object has been created, several methods are available to perform a computation on the grouped data.

how to use two columns in group by - This is Pythons closest equivalent to dplyrs groupby  summarise logic

These operations are similar to theaggregating API, window functions API, and resample API. The GROUP BY clause is an optional clause of the SELECT statement that combines rows into groups based on matching values in specified columns. In this article, I share a technique for computing ad-hoc aggregations that can involve multiple columns. This technique is easy to use and adapt for your needs, and results in code that's straight forward to interpret. To read it into memory with the proper dyptes, you need a helper function to parse the timestamp column.

how to use two columns in group by - Heres a quick example of how to group on one or multiple columns and summarise data with aggregation functions using Pandas

This is because it's expressed as the number of milliseconds since the Unix epoch, rather than fractional seconds, which is the convention. Similar to what you did before, you can use the Categorical dtype to efficiently encode columns that have a relatively small number of unique values relative to the column length. It can be difficult to inspect df.groupby("state") because it does virtually none of these things until you do something with the resulting object. It delays virtually every part of the split-apply-combine process until you invoke a method on it.

how to use two columns in group by - It filters non-aggregated rows before the rows are grouped together

The WITH ROLLUP modifer adds extra rows to the resultset that represent super-aggregate summaries. For a full description with examples, see SELECT WITH ROLLUP. The describe() output varies depending on whether you apply it to a numeric or character column.
