My machine uses Windows 7 and it has encountered a strange issue recently.
If I delete a file or uninstall a program ( and I make sure they are gone ) then I restart the machine, right after the restart that file/program will still be there, like it is being rolled back Now I can't modify anything like change wallpaper, delete files, etc. because after restart, they will be back.
Moreover, I can't install any new driver for my graphic card too ( I use Nvidia Quadro 4000 )...
Please help me with this issue, thank you.
