I know the answer to this question is floating around in this forum somewhere but I can't search so I'll just ask.

What's the special code for displaying the contents of the desktop? For "My Computer" it's {20D04FE0-3AEA-1069-A2D8-08002B30309D} and "My Documents" it's {450D8FBA-AD25-11D0-98A8-0800361B1103} and I'm pretty sure there is one for the desktop.

Note that I'm not looking for $Desktop$.

I know of no classid thingy.
  !alert "$Desktop$"

You should be using the evar versions instead of that ugliness in your rc files...

{00021400-0000-0000-C000-000000000046}

each OS and SP tends to have a new long version. that is why using the built-in LS evars is always better.
