Stuck at "Setup is preparing your desktop"

[_matt]

BTW, I just noticed itunes in your cmd

Commands in the Setupcomplete.cmd file are executed with local system privilege.

HKLM Reg tweaks can be ran here but not HKCU which are user specific.

When can I import HKCU settings and apps?

Can I do Runonceex? Although this runs at First Logon also.
