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.

 

How do I delete registry files?

type in regedit in the search box and press enter. Then from here on, DO NOT TOUCH ANYTHING UNLESS U KNOW WHAT UR DOING!! Go to Hkey_Local_Machine > Software > Then a list of program registry keys will pop up, delete anything that is uninstalled. Make sure u backup the keys unless something goes wrong. To backup, you do: Select a group of keys on the left pane > Right click > Export > name it "whatever.reg" > save it. To import the backup, click the reg file and click "merge"

 

Crazy Registry Keys just won't Delete

Hi Jaedan,

Thank you for writing to Microsoft Community Forums.

We can imagine how difficult it could be. To delete a registry key that contains an embedded null character, you must first replace the null character with another character. We recommend you to refer

Unable to delete certain registry keys from Microsoft and try running
RegDelNull.

Disclaimer: Registry is a database in Windows that contains important information about system hardware, installed programs and settings, and profiles of each of the user accounts on the computer. Windows often reads and updates the information
in the registry.

Normally, software programs make registry changes automatically. You should not make unnecessary changes to the registry . Changing registry files incorrectly can cause Windows to stop working or make Windows report the wrong information.

Important: This section, method, or task contains steps that tell you how to modify the registry. Changing serious problem might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection,
backup the registry before you modify it. Then, you can restore the registry if a problem occurs.
