This tutorial will show you how to change the product key in Windows 11.
A Windows product key is a 25-character code used to activate Windows. It looks like this:
- PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Sometimes you may need to change the product key in Windows 11 if you used a generic key, skipped entering product key during a clean install, or want to upgrade your Windows 11 edition with a product key.
