Windows 7: Cannot Take Ownership or Delete Certain Registry Keys Win7 64

I have several monitors and one of them had had a corrupted digital EDID. I have succesfully re-written the EDID to the monitors eprom however windows still will not store this corrected key. It continues to use the original VGA keys or corrupted digital keys.
The monitor is a Viewsonic and the main key is here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY\VSC0F1F
Under that key, there are 9 subkeys. 3 for the VGA and 6 for the corrupted Digital.
When I connect only the Viewsonic monitor, it never creates another key with the corrected EDID. Even when I use a program to view the edid's, it shows up as the analog one.

I have tried several guides both here and elswhere on taking control of the keys but always it fails with
"Registry Editor could not set owner on the key currently selected, or some of its subkeys."

I tried working my way up from the lowest subkey and the same thing occurs.

What I would really like to do is completely delete the Viewsonic key and have Windows create a new key on boot up.

Have you tried this?

You know, I have been looking for a fix for 2 days and finally this morning found an article about that program PSExec which is part of Windows Sysinternals PsTools.
PsExec

This is a very powerful program that allows you to edit the registry from the System Account which is way above the Admiinistrator.
It can also be very dangerous as well.

Many, many times in the past I have struggled with difficult registry keys and spent hours trying to find ways to edit or delete them.

I will keep this program on the top of my list whenever I have to delve into registry problems in the future.
I just wished I had found this years ago.

Once I ran it from the elevated cmd prompt, It never even balked when I deleted the bad keys.

Your link was right on target however I used one less switch: psexec -s -i regedit.

I use most of the Systinternals utilities and find them to be very helpful. Mark Russinovich, the founder of Sysinternals, has moved over to Microsoft, but you can check out all of the utilities at the following site;

One of my favorites is "Process Explorer" which is a comprehensive replacement for MS's "Task Manager".

Glad my suggestion was beneficial.

I'll have to give them a try.

Thanks
