A Windows product key is a 25-character code used to activate Windows. It looks like this:
- PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Where to find your product key depends on how you got your copy of Windows.
This tutorial will show you how to find and view your product key in Windows 10 and Windows 11.
