  I never realized it was possible to register under HKCU. :)
Deanna's explanation makes sense to me. In general a
COM object is registered for use on the machine. That's
the main reason for having registration in the first place.
I have no ProgIDs at all under HKCU\Software\Classes\.
I've also written a number of DLLs in VB and none of them
registers under HKCU. And I don't see any Typelib key at
all under HKCU, which seems to indicate that nothing ever
has registered under HKCU.

   Out of curiosity, I wrote a short VBScript that creates
a dummy object:
  Set Obj = CreateObject("Slipshod.FileObject")
   MsgBox Obj.Something

  Running it with Regmon I saw WSH do 4 checks. It first
tried to open the HKCU key, then the HKLM key, then
repeated the same sequence. (This is on XP.) So it seems
to be feasible to register under HKCU, but very unusual.
