I have a KMS server setup to activate windows servers in my network. Now I am troubleshooting some permission related issue for activation. So for testing purpose, I need to deactive the windows server sometime. Is there a command can do that? The server has been activated already. I tried to use slmgr -upk, -rilc swithes to deactivate it so I can do the testing. But it seems once I use -ipk swith to install KMS client key, all activation information are still there. My need is simple, once the server got activated via KMS, how could I make it roll back to the status before activation? I am using VMWare snapshot as solution now but I think there should be a windows command can do the samething.

Hi, If you want to activate the system, use slmgr /ipk and slmgr /ato to install the key and activate the system. You can use slmgr /dlv to check the results after doing this. If you want to deactivate the system, use slmgr /upk to uninstall the key. You can also use slmgr /dlv to check the results after doing this. You cannot deactivate a system without uninstalling the key. Tim Quan
