How to check if Windows 10 22H2, 21H2, or older version is installed on your PC

Windows 10 22H2 (2022 Update) is the feature update number twelve that Microsoft released on October 18, 2022. Although this is an incremental update, it can be difficult to determine whether the latest version has already been installed on your computer.

You won’t see the “Windows 10 2022 Update” name anywhere, but every release of Windows 10 receives a version number. In this case, the newest feature update is known as version 22H2, which reflects the year (22) and part of the year (H2 or half two) that indicates the release timeframe.

If you want to check what version of Windows 10 is installed on your computer, you can use the “winver” command and the “About” settings page.

In this guide, I’ll teach you the steps to confirm whether Windows 10 22H2 is installed on your laptop or desktop, but these instructions apply to determine any version of the operating system available on your computer.

Currently, Windows 10 22H2 is the only supported version remaining, as all the releases have already reached the end of support. Also, version 22H2 will retire on October 14, 2025, and after this date, the operating system won’t receive any more security or maintenance updates, and the company will start offering technical support. 

Microsoft plans to offer an additional year of support, but it will cost you an extra $30. If you’re still on Windows 10, the best action is to upgrade immediately to Windows 11 to maintain the support.

Check if Windows 10 22H2 is installed with winver

To check if you are running Windows 10 22H2, 21H2, or another version, use these steps:

1. Open Start on Windows 10.

2. Search for winver and press Enter.

   Quick tip: You can also use the “Windows key + R” keyboard shortcut, type the winver command, and click the “OK” button.

3. Check if the “About Windows” dialog reads “Version 22H2” and “OS Build 19045.xxxx”.

If the dialog shows “Version 21H2” along with “OS Build 19045.xxx” or a higher build number, then Windows 10 2022 Update is installed on your laptop or desktop computer.

Check if Windows 10 22H2 is installed with Settings

To confirm the device has the Windows 10 22H2 installed with the Settings app, use these steps:

1. Open Settings.

2. Click on System.

3. Click on About.

4. Check under the “Windows specifications” section and confirm the “Version” field reads “22H2, and the “OS build” number reads “19045.xxxx”.

   

If the “About” page shows the 22H2 number and the build number is equal to or higher than “19045.xxxx,” you are running the Windows 10 2022 Update.

If the device doesn’t have the newest version of Windows, you can upgrade it through Windows Update or perform a clean installation of version 22H2.
