Sounds very much like a problem I had. You've got to get the drives/partions to stop looking at each other.

Look at my previous post. 10tp will eat restore points on 7 or 8.1. It sees it as an "earlier" version and is protecting itself, in a way..

Gotta keep them blind to each other.

Interesting! I've tried this but it didn't work. I even posted in the Insider TechNet forum and it was suggested by a MSVP. This fix is all over the Net but I just looked at your REG file. I just noticed that there was a typo in the MSVP suggested and other places. The ":" as in "E:" was left out. I'll have to try this. I see that it's correctly given in a Windows Seven Forum as well but I didn't catch the typo. My bad!!
