It’s been a while since I was in a role that required me to worry about Windows activation’s, but yet here I am.

User entered a ticket saying they had < 30 days remaining on their Windows activation and to contact their sys admin team for support.

Running the following commands without the prepend “cscript” will show the active user interface a vbscript popup. Since I like to perform my actions behind the scenes, cscript allows me to have a remote command prompt with no user interaction required.

Check current settings

cscript slmgr.vbs -dli

Change KMS Server

cscript slmgr.vbs -skms dnsnameofyourserverhere.tld

Activate

cscript slmgr.vbs -ato
