Yikes. Don't use that then. You can do something similar (and might learn more along the way) by populating a list of services along with their current state (auto/manual/disabled) in the image management menu by pressing (*). Then just copy and paste the service portion of the list. When ready to revert the changes just apply the service list (live or directly to the vhdx) to restore your previous services configuation in the registry. Except for anything thats been deleted of course.
