Windows 10: I accidently delete .NET registry keys which is use by windows update

I accidently deleted .NET registry keys when I'm trying to fix windows update with this error code: 0x800f081f. Then I also want to clean things that was heavy in my computer so I use Ccleaner. It deletes all the cache and the previous restore points. I had a lot of restore points but I can't restore because it was deleted. Can anyone please help?

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.

 

Accidently deleted a registry key in Regedit

I accidently deleted a registry key value located in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection. I was attempting to delete one that I had previously created earlier this evening for another attempted fix (AllowTelemetry).
The deleted item was also a REG_DWORD, which is how I mistook it for the file I intended to delete, and already existed in that location prior to my visit. Unfortunately, I neglected to create a backup. Given the info provided, could anyone take a good guess
at what this value might have been so I can recreate it myself?

 

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.
