Create an account like ASPNET?

[deostroll]

I am wondering if it is possible to create an account like ASPNET. This
account does not show up on the login screen. I want to create something
similar but with more privileges.

TweakUI allows you to choose which user accounts appear on the Welcome
Screen. Other than that, you cannot create a hidden user account on
Windows XP.

Aspnet is not a real user account, in that it's not used for day-to-day
computing. It is created by installing the .Net Framework, for use by
developers.
