I think I created a problem after attempting to manage "User" properties. I try to create a new folder on my desktop and get a "c:\ access denied" error message. Can not select the "C" drive to view its contents in Windows Explorer, either- get the same message. If I choose "Properties," it shows the pi chart and indicates it is full....which I know can not be accurate- just before I had this issue, I had checked this and seen the pie indicating on 25% utilized (one minute later- no access and 100% utilized). Anyone have suggestions?
