As time passes your registry will inevitably end up with many extra...or "orphan" keys and subkeys. BUT unless you are having some sort of an issue, they are not a problem. All these so called "registry cleaners" do NOTHING to improve performance, as your system will function just fine by leaving them where they are.
Bleepin' computer does not recommend ANY REGISTRY CLEANER OR PC TUNE UP SOFTWARE, AS THEY OFTEN CAUSE MORE PROBLEMS! AND NEITHER DO I!
ALL THIS HYPE ABOUT LEFTOVER ENTRIES IS JUST THAT....HYPE! LET THE REGISTRY BE! IF YOU HAVE A PROBLEM, THAT'S ANOTHER STORY, BUT UNTIL THAT TIME... DON'T WORRY.
I will recommend CCleaner, which I've been using for many years. It's the most reliable cleanup tool out there..remove all kinds of leftover files and junk that you don't need.
It does have a registry cleaner, which removes orphaned entries, and I've never had any problems with it... but be sure to say yes when it asks you if you want to back up the .reg files.
NOTE: If you do install CCleaner, go to options>monitoring and uncheck the active monitoring feature. It's new and unnecessary. just clean up your system when the mood strikes you.
PS...Ignore the " Advanced options" under the Windows tab.
EDIT: AS FAR AS THE REGISTRY GOES... DON'T BE CONCERNED. INSTALL WHAT YOU NEED TO... UNINSTALL WHAT YOU NEED TO.... IF YOU HAVE ANY ISSUES, THEN YOU ADDRESS THEM, BUT THE REGISTRY WILL NEVER BE AS IT WAS WHEN YOU TOOK YOUR COMPUTER OUT OF THE BOX. IT WILL REFLECT ALL YOU'VE DONE WITH YOUR SYSTEM.
