Windows 10: Unable to delete registry key despite using security tab and Registry DeleteEx

Hello everyone. I've been trying to delete some leftover registry keys from uninstalling Workspace One. I get "Error while deleting key," and nothing I do can delete it. Any help would be appreciated.

ATITool registry key

Hello,

During ATITool installation, the following registry key was added to my registry:

"HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{85b5ddd0-e090-4b15-bdf2-a443a3ca0b66}"

After uninstalling the program, this key remained. I tried to delete it through the registry editor but it returned the following error:

"Cannot delete {85b5ddd0-e090-4b15-bdf2-a443a3ca0b66}: Error while deleting key."

I'm running Vista Home Premium 32-bit by the way. I also tried to change permissions for the key and deleting in safe mode, but neither of those worked either.

Any ideas on how i can remove this key? Any help is appreciated, thanks.

 

Macromedia Flash registry keys non deletable?

Hello, friends.
On friend machine I made the mistake of installing the Adobe Macromedia Flash, instead of just depacking the installer and copy over the relevant files in Firefox plugins. As result, there are several non-deletable (regeditor refuse to delete them, CCleaner did not delete them as well) registry entries:




Both from Flash 9b and 10b versions as you can see in the image. Since regedit refuse the delete the keys AND CCleaner also refuse to delete them, I tried even the Registry Booster, yet this one did not even list them as error. If that is significant, I don't know. I just want them to "go away" and don't know how.
Thinking about Windows PE boot, but not sure if that is safe and if that will allow well me to manipulate with registry... Is not there any other way? There is NOTHING from the flash files in Windows directory at all. All are removed/deleted. I stick with the
flashplayer.xpt
NPSWF32.dll
NPSWF32_FlashUtil.exe
files extracted from the install and put in Firefox / Plugins, so I will not ever install that crap again. Never did on my machine and no problemo. But in case someone do, is there a known way to fix this? Using the Adobe utility to clean up is NOT the way to do...
Also installing new version did not seems to fix a thing.

 

Can NOT remove ATITool registry key!

This is a bug report system. Undeletable registry keys and services left running after uninstall are pretty major bugs, you twit.

I finally managed to delete it via BartPE and registry editor PE.
