Sorry - Click Start and in search type services.msc click the link at the top and in the Services window scroll down to Volume Shadow Copy and see if its set to manual please.
Yes back to how it was please, I'm beginning to think you may have a corruption could you perform a Startup Repair instructions are here > https://www.w7forums.com/startup-repair-t441.html if there is a problem Windows should find it and repair it.
I used wndows easy transfer when I upgraded and it screwed up my email account had to make new one as I couldnt use contacts as address book, I wonder if its caused something here
Well the next step i would be considering would be backup all you need to keep and perform a new clean install as we have tried settings and Windows cant find the problem, I'm sorry but this is what i would do now.
