It's tough, I know, but you've got to be real careful with the repairs from this program using it on Insider Preview. It's like trying to walk on eggs and not breaking them in the process. Dangerous as hell. I only use it for tweaking very little. Sfc scan, checking variables, etc.
I tried running a few fixes and created a disaster. Messed up my updates when trying to repair.
I have decided to park it for a while until on a solid build.
BE CAREFUL TO ALL!
