Windows 10: Accidentaly Deleted my Uninstall Registry Key for a downladed Program. HELP

Hello i accidentally deleted a programs uninstall key that i downloaded. it doesn't show where i can uninstall the program vortex under control panel or the registry Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ and i keep getting an error when starting the program saying no Uninstall registry.


Is it possible i can restore / make a new Registry if that is even possible. also there is no way i can reset my PC unfortunately i don't have a back up because i don't have the HDD space to save a full backup of my PC.


this is the form that i used to see if it was actual deleted and i cant find it in the uninstall list. https://answers.microsoft.com/en-us/windows/forum/windows_vista-windows_programs/want-to-uninstall-program-not-showing-on/22f85f0c-3062-49be-886f-8a823e5314d9

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.

 

Deleting an uninstalled software

Hello,

Thank you for your interest in Windows 10.

First, I would suggest you to contact Python if they have any uninstaller, if yes, run the uninstaller package to get all the remnants of python removed completely from your computer.

If that does not help you may edit the registry and remove all the values for python. Follow the steps below to do so:

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added
protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge

  Currently installed programs list of Add or Remove Programs, right-click the key in the left pane of the
  Registry Editor window, and then click Delete.
  
  Click Yes in response to the "Are you sure you want to delete this key and all of its subkeys?" message.
