Vista: Administrator account cannot change or see system settings

Question

Running from the administrator account doesn't let me change or even see system settings!

Info:

• I'm logged into the Administrator account
• I've turned off UAC in the registry
• I've turned off firewall and windows defender (no AV installed)

If I try any of the following nothing happens:

• control.exe system
• Pressing network or sharing center
• Pressing any user access settings (can change password etc. from the command line though, and is allowed to change settings in the registry)
• Start windows update

There doesn't seem to be logged any errors when I try any of these things.

Running in safe mode doesn't help either.

This is running Vista Home Basic SP1 on an Advent laptop.

Answer 1

Well.. Reinstalled the OS, and now it works. It has worked for many months, so I hope it wont happen again.
