Sometimes when you uninstall a program and the uninstaller turns out be be corrupt, you have to manually remove the program from your computer by deleting the folders and shortcuts. But how will you remove registry items? Some of these registry items are left due to program errors, misapplied registry hacks, etc. Problems also arise when users transfer or delete programs without realizing that many registry entries are aiming to the old location. When such unwanted registry keys are left untouched, it can directly effect your computer’s stability and performance.
There are many registry cleaners out there like CCleaner, etc, but one tool has recently garnered my attention. Little Registry Cleaner is a free opensource utility for cleaning obsolete or unwanted items from Windows Registry.
