Remove Certain Registry Keys

I need to remove two MFG registry keys and two HardwareID registry keys. I don't know how, it says unable to delete selected values. I'm uninstalling PowerDVD 12 and i want to remove all its registry keys whatsoever, I'm down to these four. Any help would be appreciated.

I removed everything using all tools possible then manual removal, all that's left are the keys i mentioned.

 

What are these keys? Specifically?
Can you post a pic of the error message?
Are you sure they aren't required for something else?

Are you seeing degraded performance by leaving these keys as is? What are they doing that requires you to remove them?

 

If your computer is operating fine, there's nothing whatsoever to be gained by removing these keys. There is much to lose by tinkering with the registry.

 

I need to remove them for personal reasons to fully uninstall Cyberlink.
the same for the Mfg registry key and two identical key but in another folder.

 

Note: To anyone that follows the following, you do so at your own risk. So create a restore point before proceeding.

To do this you'll need to run regedit as system.
Download Sysinternals PsExec, make a directory for it and extract the zip file to the created directory.

Here's a simple batch file to launch Regedit as System, you just need to change the file path to where psexec.exe is located.
Paste the following into notepad and save as type: All files - name: Regedit++.bat

Code:

@echo off
for /F "tokens=1,2*" %%x in ('bcdedit') do set adminTest=%%x
if (%adminTest%)==(Access) goto not_admin

REM Edit the file paths
"C:\edit the path\PsExec" -s -i -d "C:\Windows\regedit.exe"
goto finish

:not_admin
echo You must run this script as administrator!
pause
goto finish 

:finish

Right click and run the batch file as Administrator.

 

Are you running regedit.exe as an administrator? Even if you are on XP it might work if you run regedit as the default administrator.
