HOW TO: Check the version of your Windows 10
The new Settings app offers build edition, and version information in a user-friendly form.
Find your Edition and Build number with Winver
1) Hit Start, type “winver,” and then press Enter. You could also press Windows Key + R, type “winver” into the Run dialog, and press Enter.
The second line in the “About Windows” box tells you which version and build of Windows 10 you have. Remember, the version number is in the form YYMM—so 1607 means the 7th month of 2016. A couple of lines down, you’ll see the edition of Windows 10 you’re using—Windows 10 Pro in our example.
The “About Windows” box does not show whether you’re using a 64-bit or 32-bit version of Windows 10, but it does give you a quicker way to check your version and build than navigating through the Settings app.
