Fixes issue with Windows Updates not successfully running on a Windows 7 build

Seems to have fixed it. Just waiting on my runs to finish to verify, hopefully sometime this weekend I'll be able to confirm a working build with this fix.
I think possibly that comment needs to be removed, however dis-updates.ps1 might interfere with the update script (I think updates might need to be enabled in order for the update script to work? Could be wrong... just going from memory)
