Windows 7: Can NOT delete any registry key in HKLM/SYSTEM

Can NOT delete any registry key in HKLM/SYSTEM

I have Windows 7 Ultimate, and every time i want to delete a key in HKLM/SYSTEM, i get "Cannot delete (key name): Error while deleting key" Here's what i've tried: setting Permissions on the key to full control for administrators group, owner, owner rights, SYSTEM, and my own admin account, NONE of that helps. Also, in 'Advanced security settings-->Owner, i changed it to my own admin account, and also ticked "replace owner on subcontainers and objects" but i get another error "Registry Editor could not set owner on the key currently selected, or some its subkeys." I even turned off User Account Control (UAC). What gives? Some help would be great.

Thanks in advance.

You're trying to delete the entire "SYSTEM" tree?

Invoke the registry editor (regedit.exe) with administrative privileges (right-click, Run as administrator).

Well, after restarting my PC, i noticed some of the keys i wanted to delete are either gone or blanked out. Now, i followed the M$ link : how to add, modify, or delete registry subkeys... and while it said "The keys and values contained in have been successfully added to registry", the key is STILL present in registry Also, right-clicking regedit.exe and "Run As Administrator" did NOT help either. Any other suggestions?

run Ccleaner registry cleaner and those blank registry keys should be removed. You could have malware/virus on your machine as well.
