Problems with the Windows Registry are a common cause of Windows crashes, slow performance and error messages. Registry problems can occur for many reasons, including references left behind after un-installation; incorrect removal of software; missing or corrupt hardware drivers; or orphaned start-up programs. This will significantly increase the Registry size and slow down your computer, because Windows will need more time to load, search, and read data from the Registry. Scan and repair your registry and make your PC run faster, cleaner and error with ACleaner. It provides a list of all errors that were found, and you can choose to remove all items, or only selected errors. Before the program deletes any keys, it automatically creates a backup of the registry and allows you to easily undo any changes if needed. You can choose to scan the entire registry or only selected sections.
