Before You Begin
Microsoft enables various ways of activation, such as using digital licenses based on your Microsoft account or typing in product keys in the process of installation. In case of a recent drastic hardware upgrade (e.g., a motherboard replacement), you might be asked to re-activate your copy of Windows with the same Microsoft account that was associated with the license.
Another thing to note prior to doing so is that you must confirm that you are actually using Windows 11 and that the operating system is completely updated. This can be easily checked by locating and opening up the winver tool.

This gives you your version and build number of Windows. Unless your device is already running Windows 11, you will first have to update to it, as a large number of the activation features and fixes are only available to Windows 11.
