KMS is something you login to once in a blue moon and then you wonder how the heck are you supposed to install a license key and verify that it got added correctly. So as a reminder to myself.
To install a license key:
slmgr.vbs /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Then activate it:
If you want to check that it was added correctly:
cscript slmgr.vbs /dli all
cscript so that the output comes in the command prompt itself and I can scroll up and down (or put into a text file) as opposed to a GUI window which I can’t navigate.
