Function: GetShellFolders

Simple script retrieving shell paths from these keys: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders and HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders.
It deals well with registry values whose names are GUIDs. Spaces in value names are replaced with underline character (for instance, My Music -> My_Music). Look at the screenshot below the code, it speaks for itself. Comments in the code explain how to use it. The code is in beta.
EDIT: Updated to support Windows 2000 and Windows 2003, and to deal with empty registry values.
Tested/working in Windows 2000, XP, 2003, 2008, Vista and 7. Some diacritic characters may cause troubles in Windows 2000.

Go there, click the file GetShellFolders.cmd, and then click "Download".
