Creating an user account in Minisetup?

[mahcih03]

Is it possible to create user accounts (like in Windows OOBE) directly from Minisetup? There's only a step about the user and organization names, but that's not what I'm looking for.
I'm choosing Minisetup instead of Windows Welcome because it detects PnP devices before anything else. I'm also using it because I'm working on a project of making Windows XP on par with modern OSes in as many aspects as possible, and I need to sysprep it in order to capture it and install it from PE.

PS: Found the user account creation dialog in syssetup.dll using ResHacker (Dialog 56 : 1033), but for some reason it never shows up on neither Windows XP nor Server 2k3
