How to see detailed Windows version

You may need to check your Windows version for various reasons such as upgrade purposes or application compatibility issues. The easiest way to see the version is right clicking “This PC” icon (or “My Computer”) on your desktop and selecting “Properties”:

As you see in the screenshot above, “Properties” window shows the main version number (Windows 10) but it doesn’t tell the sub-version or build number (something like 10.0.15132 Build 15132).

Check detailed Windows version

Here are 3 ways to see the Windows version with details (it works in Windows Server too).

Method 1: “systeminfo”

Go to “Start”. Search for “Command Prompt”. Open it. Type systeminfo.

Some of the information you can display with systeminfo command:

  • Windows version and build
  • Manufacturer and owner
  • Installation date and boot time
  • Time zone
  • Domain and logon server
  • Network cards
  • Virtual memory
  • Hotfixes installed

If you want to show filter only operating system information, type systeminfo | findstr OS (Thanks to iWeb).

Method 2: “winver”

Go to “Start”. Search for “Command Prompt”. Open it. Type winver.

winver command display less information than systeminfo does but it opens a user-friendly window which might be more preferable for some users.

Method 3: “msinfo32”

Go to “Start”. Search for “run”. Open it. Type msinfo32. Click “OK”.

  • Windows and System directories

  • Processor speed 
  • Memory capacity
  • System drivers and services
  • Network connections
  • Graphic card and monitors

Difference between Mainstream Support and Extended Support

One of the questions asked most about Microsoft’s licensing policy is the scope of Extended Support. What does it mean and how long does it last? Who can leverage it?

Microsoft provides 5 years of support for almost all software products including operating systems such as Windows and Windows Server. It also covers development and database tools such as Visual Studio and SQL Server. This initial support period is called Mainstream Support. All security updates, new feature developments, and complimentary support are provided during Mainstream Support. For the end of support dates for Windows Server, check this post out.

Microsoft Extended Support

After the 5-year mainstream support, a new period called Extended Support starts. During the extended support, Microsoft still provides all security updates. However, unlike mainstream support, product design change or new feature addition requests are not accepted and complimentary support is not provided.

Difference between Mainstream and Extended Support

The table below shows the details of support types (Courtesy of Microsoft).

 Type of support Mainstream Support Extended Support
Request to change product design and features  Available  Not available
Security updates  Available  Available
Non-security updates  Available
  • Available only with Extended Hotfix Support
  • Not available for desktop operating system consumer products
Complimentary support1included with license, licensing program2 or other no-charge support programs  Available  Not available3
Paid-support (including pay-per-incident premier and essential support)  Available  Available

1 Refers to phone and online support options.
2 For example, support incidents acquired through the Software Assurance program for server products.
3 Limited complimentary support may be available (varies by product).

For detailed information, please visit Microsoft’s Product Life Cycle Policy page.

As a summary, the in Extended support:

  • No new features are added
  • Complimentary support is not available
  • Non-security fixes are available only if Extended Hotfix Support is purchased
  • Security fixes are available just like Mainstream Support

What is the end of support date for Windows Server?

The growing security threats in digital life and constant need for improved features forces companies to have reasonable end of support date for their Windows Server systems. Microsoft made support timelines easy to find and easy to understand. Let’s have a look at them.

Long story short; Microsoft provides 5 years of support for almost all software products including operating systems such as Windows and Windows Server, development and database tools such as Visual Studio and SQL Server, or other enterprise level products like Exchange Server.

Windows server end of support

In addition to the 5-year support which is called “Mainstream Support”, Microsoft also offers another 5-year support with a smaller scope. The second 5-year period is called “Extended Support”. Therefore, a Windows Server version that was released in 2012 has support until 2022 (Please check the table below for detailed end of support dates).

During the extended support, Microsoft still provides all security updates. However, product design change or new feature addition requests are not accepted during this period.

Thanks to Mirazon for this detailed table. For more specific dates and instructions, check Microsoft’s “Product lifecycle” page.

When searching for end of support dates, make sure to distinguish dates for regular server version and R2 version. R2 version of operating systems include all cumulative updates until a certain date so they have a longer support period. For instance, Windows Server 2008 had support until 2011 while Windows Server 2008 R2 has support until 2020.
