When you open Windows Explorer or My Computer, the Folders bar does not contain any icons.
This behavior can occur if there is no C: drive on your computer.
To workaround this behavior:
1. Using Notepad, create a cdrive.bat file, in your My Documents folder, that contains:
call :drive "%windir%"
subst C: %dl%
2. Create a Minimized shortcut to the cdrive.bat file and place it in your Startup folder.
3. Logoff and logon to Windows XP.
