Locate your product key for Windows 10 or Windows 11
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.
Where to find your product key depends on how you got your copy of Windows.
