Restore Default Shell Folders are three .reg files to restore the default locations of the most common folders (Pictures, Documents, Videos) as detailed here.

Geeks can manually navigate to Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders and Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders, right-click on the folder that's moved and select Modify. Here, you can enter the correct path if it was moved. That said, if you're not familiar with the registry, backup first or better yet, use the reset scripts. In the screenshot below, we are using the My Video folder as an example. As you can see, most of these default folders should be %USERPROFILE%Videos so if yours isn't; you can change it back.

While we're discussing it, backup before you proceed. Tweaking.Com Windows Repair has an easy to use Registry Backup and we've also sent this fix in as a suggestion for future repairs in the program.
