What Is The Windows Registry?

The majority of file opening problems are caused by errors in the Windows Registry.

The Windows Registry is a directory which stores settings and options for Microsoft Windows operating systems. It contains information and settings for all the hardware, operating system software, most non-operating system software, and per-user settings.   If necessary, you can manually edit the registry by doing the following:

1.  Hit Start Button
2.  Select "Run"
3.  Type regedit and then hit the enter key

Any change you make in the registry is saved automatically.
