Latest:
I booted in Safe Mode with networking. Ran CMD prompt as Administrator and performed sfc /scannow.
Windows Resource Protection found corrupt files but was unable to fix some of them. Details in log (haven't found that yet).
Opened Service Console. Noticed 'Volume Shadow Copy' is set to automatic.
Still confused by
Application Information Service. Sorry, I'm probably being a bit dumb here.Still can't create a restore point, I'm giving this a break for the night!
