How To Identify Your Version of Windows 10

Posted March 2018 by Steve Sinchak

With the launch of Windows 10, Microsoft switched to a new release cycle with major releases that occur about twice a year. All of these updates are released under the Windows 10 brand which can make it a little confusing to determine which version of Windows 10 you have. But there is a simple trick to identify when your version of Windows 10 was released.

Microsoft uses two numbers to distinguish between Windows 10 updates. The version number is made up of the last to digits of the year of the release, along with a two-digit month. For example, the Fall Creators Update to Windows 10 has the version number 1709 because it was released in 2017 in the month of September.

The build number is another unique identifier that simply increments over time. The build number for the Fall Creators update to Windows 10 is 16299. There are a few ways to identify the version and build number of your PC.

Option 1:

  1. Click on the Start Button.
  2. Type in About your PC and hit Enter.
  3. Scroll down to the Windows Specification section.

Option 2:

  1. Click on the Start Button.
  2. Type in winver and hit Enter.
