Solved How to delete admin account

[Tonchi]

I am also curious to find that out. It is always interesting to learn something new about Windows.

From here:
Critical System Services (Windows)

the process killed might be smss.exe, csrss.exe, wininit.exe, logonui.exe, lsass.exe, services.exe, winlogon.exe, System, svchost.exe with RPCSS, and svchost.exe with Dcom/PnP.

​i love shutting down this process for force crash xD

I was unable to reproduce Tonchi's problem by following the steps suggested in this thread, namely:
1. Deleting the built-in Administrator - didn't work, error 1371
2. Disabling the built-in Administrator - worked (from under its account)

The built-in Administrator lost an ability to log on, which is expected. However, this had absolutely no effect on the other administrative account created during the installation. I guess something else was done to mess up the system.

Correct, something happened to the user profile so the other administrative user lost it's privilege.
Could be either a file corruption or virus.
