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.

 

Unknown User Account created after upgrading to windows 10. It comes back if I delete it.

Original Title: Unknown User Account

Hello,

Since I upgraded to Windows 10 I am seeing an account that I did NOT create. So I deleted it by going into Control Panel > All Control Panel Items > User Accounts > Manage Accounts then I click on the unknown user account and delete it. That said.... It
comes back. I have also followed the below suggestions from other posts and still does not seem to work.

Let’s try simple steps and check if the user account is detecting and try removing it.

• 
  Press Windows key + R, type netplwiz and press Enter.
  
• 
  Check if the user account is appearing on the list.
  
  
• Click on user account and click on Remove. (If user account appear on the list).

Please advise.

Thank you

 

Is there a way to repair your registry without deleting it?

I thought that sfc /scannow would work but I don't think it repairs the registry, just the .dlls.
Is there a command that repairs the registry without having to repair XP entirely? I have found that a screwed up registry is the main cause of slow bootup times. But I don't know how to repair it without deleting the registry commands of programs already installed. All I really like to do is add those commands that may have been deleted by mistake or made corrupt by mistake.

Is there a way to do this?
