License upgrade (pro to enterprise)

We recently discovered that a handful of our machines have been setup using windows 10 Pro, not enterprise. A quick google around says I can just use slmgr /ipk to replace the key with the enterprise key however this doesnt seem to work as expected.

When i run this, the key changes as you would expect but the resultant version doesnt look right.

Before
Name: Windows(R), Professional edition
Description: Windows(R) Operating System, RETAIL channel
Product Key Channel: Retail
License Status: Licensed

After
Name: Windows(R), ProfessionalWorkstation edition
Description: Windows(R) Operating System, VOLUME_KMS_W10 channel
Product Key Channel: Volume:CSVLK
License Status: Licensed

Any idea what I'm doing wrong? This was using the KMS key that they should already be using. Or should I use the MAK key with slmgr?

I have about 40 machines to update, and I want to avoid having to manually activate each one, so we just want to push the right key onto the machines.

Were you using your KMS license key from your EA on the workstation by chance? You don’t want to use that key, it should only live in the KMS. You’d want to use a KMS client key, as found here:


You can still do slmgr.vbs /ipk with the above and then the system should go looking for the KMS.
