If you feel like sky is about to fall on your head because you couldn’t find out which build and version of Windows 10 is installed on your computer, don’t feel bad, you are not alone. Though checking build number is easy once you know it, Microsoft has some reason decided not to show it in the ‘This PC’ > ‘Properties’ right-click context menu. It only shows the Windows 10 edition, whether it’s a 64-bit machine, and Windows activation status. This is the place where almost all users first takes a look to find anything related to Windows installed version. So where is it gone?
Microsoft has chosen to go the Android and iOS way of putting the build number and version details in the ‘About’ page of the ‘Settings’ app, so mostly targeted for tablet users, or may be let me put it in other way – Windows 10 settings app is more of touch friendly.
Click ‘Action Center’ icon on taskbar and launch ‘All Settings’.
In the left pane, click on the last link that says ‘About’. Now you will see pretty much all details of Windows 10 you need including OS Build and Version.
