Simple way in XP (same as Hipster Doofus, but less typing):
Copy and paste this into a .txt file...
--------------------------------------------------------
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder]
"Attributes"=hex:50,01,00,20
"CallForAttributes"=dword:00000000
--------------------------------------------------------
(don't copy dashed lines, just whats between)
Rename the .txt file to .reg - double click the file, add the info to your registry. Easy as pie.
