Yes, I mean Volume Shadow Copy Service - it's just I'm so tired of typing the thing, I shortened it
I'm not dual booting - I've been through all the easy options on Google
What is disk management programme? if it's things like Registry cleaners or defrag, I've tested them all. I have Acronis TrueImage and am tryig to get an answer from them, so far without success. I don't want to take it off, as it is my only decent fall back device in Win 8.1
I'm not sure if I've tested a clean boot for this - I've tested it for something or other in the last 6 weeks - I'll give it a go, though I sometimes have to wait 2-3 days to see if there is an effect. I'll give it another go
I'm the only user
Sometimes (quite often), they go after a power down and restart (not sure anoty logoff/restart) but the power down and restarts I've already tested this morning (between 4 and 7 am) have not wiped my manual test restore point
