How to clean and repair invalid registry entries and errors in Windows?

The registry is a database that contains information and settings for all the hardware, software, and user preferences of your computer. When you install, uninstall, or simply use software programs, registry entries are created, modified, or deleted. If you uninstall an application incorrectly or an error occurs during the uninstall process, the registry entries belonging to the application may remain in the registry. This may also happen if a file referenced from the registry gets deleted. As a result, the registry gets stuffed with invalid and orphaned entries. Many invalid records remain in the registry long after the corresponding applications have been removed. This slows down your computer and can cause errors in other installed programs. To avoid problems with your software and optimize the performance of your computer, these invalid entries must be deleted.
