VirtualStore is a pain in my tuchus. If you don't know what this is, count yourself fortunate. I'll save you the gory details, but Microsoft screwed yet ANOTHER class of users by making Virtualstore active by default -with a flawed implementation- in Windows 7. Thanks, jerks.
At least it isn't costing me money. Unlike this guy, who brightened my day by taking some extra time to give quality answers to the trolls an lusers who can't understand.
