I have an EC2 Instance Windows Server Datacenter 2008, and I'm getting an "Unable to Activate Windows" message. Even after following through the instructions here

For some reason, the Registered KMS Machine name wasn't set. When I ran:
slmgr /dlv
There was no "Key Management Service client information" section.
The fix then, was to run the following to manually set a KMS:
slmgr /skms 169.254.169.250:1688
After which, you can activate windows again with the following:
slmgr /ato
