I'm not chasing anything, just deleting dead entries. You do it your way and I'll do it mine. I'm well aware it is not necessary but I do it anyway.

Check this out. Ran it with no issues...
I knew someone would say this and some people don't recommend reg cleaners but lots of games and progs leave behind their reg entries after an uninstall and I like to see this crap removed from my PC. No, I am not going to go through the hassle...
I still have ccleaner installed but rarely use it. I wouldn't buy it though. Microsoft have a free app for removing junk files, PC Manager, get it from the Microsoft store.
