Causes of Registry Errors

Windows registry is a database that stores crucial settings and options of the Microsoft Windows operating system. Registry entries are created for each application and driver installed on your computer. When running, programs may access the registry thousands of times per second.

Just like any other database, the registry becomes a real mess without proper maintenance. When you uninstall programs, invalid entries can be left behind and cause various conflicts between 3-rd party applications and the operating system. As a result, your system may become unstable.
