Did you try solution 2 on this site? I'm not sure if repairing Windows will fix the problem. You may want to try creating a new user account first, and migrating your files and settings to the new one. Otherwise, it sounds more like a registry issue where several keys would have to be manually reverted back. There are guides on the internet that can help you change them back, but they must be used with care as improper modification of the registry can make matters worse if you don't know what you are doing.
I was trying to move my Documents and Desktop folders to my newly installed Hard Drive, but I accidentally did something.   I merged the Desktop folder and the Z: Hard Drive.      There's no desktop folder inside the HardDrive, but the HardDrive is the folder itself.   I can't reverse it cuz it says I can't move a parent folder to a child folder.   Will a windows reinstall solve this issue ?   Is there any other way ?     [IMAGE]   [IMAGE]
