Finding out when Windows was installed on your computer can be useful for troubleshooting, auditing, or just out of curiosity.

This guide shows how to check your Windows installation date using CMD, PowerShell, Windows Terminal, and the Windows Settings App.

    systeminfo | find /i "Original Install Date"
  3. You will see the Original Install Date listed in the output.

Using PowerShell

  1. Open PowerShell by typing PowerShell in the Windows search bar and pressing Enter.
