The Windows registry is the central storage area for important preference and settings files that tell your computer how to run all the software and hardware that’s installed on your PC.  The registry is very important to the Windows operating system, and problems in the registry can cause severe malfunctions with the way your computer runs.  It’s not recommended that you attempt to fix the registry manually if you are having problems.

Instead, get yourself the best registry cleaner available and use it to help you clean the registry of all the corruption and clutter that tends to build up over time.  The biggest offender to registry problems is the incomplete uninstallation of software and hardware, which tends to leave behind the registry entries of old programs that you’re trying to remove.  This can cause conflicts and also cause the computer to bog down.
