It's quite normal for registry keys and program folders to be left behind after uninstalling something. Very few applications can manage to remove everything associated with it, but those leftovers rarely do any harm other than waste a negligible ammount of disk space.

We don't recommend meddling with the registry at all as you can easily 'break' Windows, but if you are competent you should first back up the registry then delete the redundant keys. Just be careful you don't delete anything else, be sure it's the correct key in the Registry or the correct folder in Program Files that you are deleting. At a bare minimum you should back up the Registry first, though ideally you should first create an entire disk image on an external hard drive before doing anything which carries a risk of 'breaking' Windows.

I make regular disk-images of my desktop PC & laptop because I'm constantly testing software then subsequently removing redundant folders and registry keys. Been doing that for years so i regard myself as very competent and I'm always prepared for the worst, but anyone who is less prepared or less experienced just needs to ask themself "If it's doing no harm should I leave it alone?". I would advise "Yes".

What about some of these uninstall programs that are supposed to remove all the old left behind files?

You can see if Revo Uninstaller will pick up any. Other than that...Leave the registry alone!
