So you mean that built-in accounts may also be renamed as desired at that stage? BTW, there is a common problem that all your dialog windows do not account for various screen resolutions. You write and test everything at standard 96 DPI screen; I use 120 DPI, aka "large fonts" (not to mention greater values, which ar econsidered as custom), and a lot of text don't fit into the window. I have to reconfigure and restart my system just to read it. Finally, I have 3 users on my system: the default Administrator, Guest, and the third is admin defined during installation. Whenever I set AutoAdminLogon=1 in Registry, it has no effect and is set back 0 after logon. What is missing?
