How to Check Which Windows Version You Have

Find out whether your PC runs Windows 11 or 10, which feature update it has (such as 24H2), and the exact build number in under a minute.

Support pages, driver downloads, and software requirements often ask which version of Windows you have. The answer has three parts: the edition (Home or Pro), the version (such as 24H2), and the build number. Two places in Windows show all three.

Open Settings

Press Windows + I. You can also right-click the Start button and choose Settings.

Go to the About page

Select System in the left sidebar, then scroll down and click About. On Windows 10, System is a tile on the main Settings page and About is the last item in the left list.

Read the Windows specifications section

Under Windows specifications you will see:

  • Edition, for example Windows 11 Pro or Windows 10 Home
  • Version, for example 24H2
  • OS build, for example 26100.4351
  • Installed on, the date of the last major install

The Device specifications section above it shows the processor, RAM, and whether the system is 64-bit.

Check with winver instead

For a quicker look, press Windows + R, type winver, and press Enter. A small About Windows box shows the version and build on one line. This works on every version of Windows and is handy when you are helping someone over the phone.

What the version number means. Since 2020 each yearly feature update is named by year and half: 22H2 shipped in the second half of 2022, 24H2 in the second half of 2024. Windows 10 stopped at 22H2. Windows 11 has had 21H2, 22H2, 23H2, 24H2, and 25H2. The build number tells you exactly how up to date the machine is; monthly patches raise only the digits after the dot, while a feature update changes the digits before it.
