Is there a proper way to activate Windows after the image process has completed? I tried using the built in vbs script but since the window it creates never returns a response the fileset sits in activating for eternity.
If you put that commandline in a BAT file and run it from a CMD window it will pop up a dialog confirming that Windows was activated successfully. That's why the fileset sits in activating status forever. It's displaying a dialog to the system account, since that's the user context the script runs under. Unfortunately you can't log into the client as the system user to dismiss this dialog so the activation can finish. Try using this for the commandline instead. It should run silently.
cscript //B "%windir%\system32\slmgr.vbs" /ato
