The back and forth Windows licensing from KMS to MAK can be so frustrating. Today I had to take a system that had been KMS and then made MAK back to KMS again. Of course this process involves searching for a variety of various scripts to run but you have to put a KMS key in even if you’re going to network provided KMS. Apparently Microsoft makes available default KMS keys you can put in to swap back.

- Find your key from the website for the version you’re working with
- Start a CMD Command Prompt as an admin
- cscript slmgr.vbs /ipk KeyFromWebsiteAbove
- cscript slmgr.vbs /ato
The Windows interface updated to show my system was now activated again without having to close it.
