Windows stores common application settings and configuration data in a central database called Windows Registry. Over time, this database can become cluttered with leftover data from no longer installed software and entries can even become corrupted. Since so many applications rely on the Registry for information, clutter and data corruption can cause noticeable performance drops and make your PC feel sluggish and unresponsive. Frequent error messages or problems when uninstalling programs can also be caused by Windows Registry issues.
