My laptop has just gone through an automatic update to Win 10. It did say it was a major update and could take some time. I restarted on the prompt and left it to it. When I came back, everything was OK, but when I came to shutdown I noticed it still said update and restart. I let it update and restart again and now I have problems. Left click on the the start button does nothing, although I have brief CPU activity. Left click gives me the menu, but not all options are working. I can't get apps or settings, although device manager works. I have lost all my favourites on both chrome and Firefox (Firefox is a different version also - I seem to have lost the most recent update). It has even changed my wallpaper.
I have tried restarting in safe mode and a system restore, but it says I don't have any restore points (I have created 2 in the last 6 months). I also tried windows repair, but this did nothing. I upgraded to 10 from 7 on the freebie offer, so I don't have an install disk, so I have not yet tried re-installing windows.
Has anybody got any ideas on how to fix this problem?
