To check which Windows operating system is installed:
- Select Start > Settings > System > About.
- Look for Edition, Version, and OS Build.
A quick alternative:
- Press Windows key + R.
- Type
winverand press Enter. - A window opens showing the Windows version and build.
From Command Prompt or PowerShell, this also works:
systeminfo | findstr /B /C:"OS Name" /B /C:"OS Version"
