I have 3 registry keys that I cannot delete. "Error opening Key"
I cannot take ownership because there is no permissions.
I have tried reg and tried to make a .reg file. no elp
The keys are
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Shell
Extensions\Approved\{46D9700D-6DAC-7507-46E7-457874290BE0}
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Shell
Extensions\Approved\{4B3E4A36-23CD-FC8D-0BB7-F8E8437CBAE0}
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Shell
Extensions\Approved\{C34915D6-DC50-AEBD-57B2-6CCDBFF763AC}

Any suggestions?
Sysinternals regnull shows as a security mismatch.

Is there a natice api program that I can run to put the valuse in that I
would like to delete? Or is there some other way to delete these keys?

Thank you in advance

You have to find the DLL that is being used and kill it. The keys are protected.

I have booted with an external WinPE disk and remote regedit. The keys are
not being protected at that point. A virus has wriiten to the keys and the
security users have been removed. I have ran into this before about two years
ago, but I cannot find the tool that I used to remove it then. All I remember
was that it was a regedit tool that was written in native API and not Windows
API. I found a couple of partial tools on Code project but they are not
complete enough to use, missing files.
Thanks for your reply.
