I've been having problems with my work PC for the past year or so and my IT dept are clueless and unwilling to help.
When I try and move certain files into a folder it states something like 'unable to move files because the files are using another process'. I've closed down all other programs but it doesn't seem to help.
My IT dept suggested a while back I close down 'explorer.exe' which I do but then I can't access anything else as my screen is completely blank except the wallpaper. I then have to restart my PC which solves the problem. IT seem to think restarting my PC several times a day is is a viable solution.
