Windows 10: I needed to buy a new product key will the install delete my files?

I am fixing up my husbands old gaming pc that he built 10 years ago and it’s still running windows 7 however the lower right corner does say it is not a genuine copy. I do not have internet access at the moment and had to buy a physical disk of windows from Walmart and don’t know if when I install if all his files and games will be deleted or not.

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.
