Cleaning your system’s registry

If you want to keep your computer working great, you need to clean the temporary files, uninstall unused programs, keep it up-to-date, keep it virus and malware free and clean the registry.

Typically cleaning the registry should be left to a computer savvy person.  Why?  Registry programs find programs that have been uninstalled and have in essence left parts of it behind.  There are tons of programs out there that will find missing pieces of programs left behind.   Three excellent programs are CCleaner,  MVRegClean and TweakNow RegCleaner.  Here’s the results of each of these programs after a run on an older computer.   It appears MVRegClean is the winner….but reading through the results shows that CCleaner and TweakNow picked up some items MVRegClean may have missed.   While MVRegCleaner is more thorough than the others, much like anti-malware products, you may have to run more than one registry cleaner.   Remember, running a registry cleaner and not verifying the entries could lead to programs not working.  Double check the entries that are being removed and always backup the registry.
