256986 Description of the Microsoft Windows Registry
When you start your computer using the Safe Mode option, you may not have access to your mouse or keyboard, or both. However, if you start the computer normally, the devices work correctly.

Similar behavior may occur when you start the computer using the Safe Mode with Networking option.

NOTE: This applies to PS/2 mouse and keyboard.
This behavior occurs because of missing or corrupted registry subkey(s).
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

    4. On the Registry menu, click Export Registry File.
    5. Save the file to a disk and give it an appropriate name.
  2. On the Windows 2000-based computer that is experiencing the problem, start Windows Explorer.
  3. Locate the file you created in the previous steps, and then double-click it.
  4. Click Yes when the following dialog box is displayed:
