How to Find Windows 11 Product Key

Last Updated : 5 Dec, 2025

A Windows product key is a 25-character code used to activate your operating system. If you’re installing or reinstalling Windows 11, you may need this key to complete the setup especially if your device didn’t come with digital activation.

If you upgraded from an already activated Windows 10/8 system, your device may use a digital license, meaning you might not need to enter the key again.
