Funny keys in NTUSER.DAT

[Richard Sharpe]

Hi,

In my quest to write a registry editor for UNIX, which will take a few 
more days, I have come across a funny key name in the NTUSER.DAT file:

Type: Sub key, Key Hash: S-1-, Key Name: 
S-1-5-21-129735678-430395340-1080627117-2002
  Owner SID: S-1-5-32-544
  Group SID: S-1-5-18
  SACL: NONE
  DACL:     ACEs: 1
     Type: Allow, Flags: 02, Perms: 000F003F, SID: S-1-5-18
  Value: Migrate : REG_DWORD : 0x2

What would this key be used for?

Regards
