System Change Product Key in Windows 11

  • Staff

A Windows product key is a 25-character code used to activate Windows. It looks like this:
Depending on how you got your copy of Windows 10 or Windows 11, you'll need either a 25-character product key or a digital license to activate it. A digital license (called a digital entitlement in Windows 10, Version 1511) is a method of activation in Windows 10 and Windows 11 that doesn't require you to enter a product key. Without one of these, you won't be able to activate your device.

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.
