A Corrupt Windows Registry

A corrupt windows registry occurs when computer registry errors cause problems with system performance. Adding a new program or driver to your system may cause registry errors, as can uninstalling programs. If you're bold enough (or foolhardy enough) to make registry changes yourself, faulty entries can also corrupt a registry.

The best way to prevent a registry from becoming corrupted is to practice regular “hands-off” maintenance. A regular PC check-up can detect registry errors and save a corrupt registry.
