The User Shell Folders key stores paths to Windows Explorer folders.

The key exists at:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

            AND

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

Entries in the User Shell Folders key take precedence over entries in the Shell Folders key.

Entries in HKEY_CURRENT_USER take precedence over entries in HKEY_LOCAL_MACHINE.

Entries in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders are NOT used in Windows 2000.

The default settings in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders are:
