As such I think you can start with Google and type in that message and see what folk are doing.

Ok so about a week ago, give or take, my computer did an automatic update, of which i turned off months ago. since the update my pc has been blocking nearly every single program I try to run, this includes media player, games, virus scanning programs, and even installers. they all give the same message, Windows cannot access the Specified device, path, or file. you may not have the appropriate permissions to access the item. PLEASE HELP!!!
