What to do if the system prompts the error "Library is not registered"

Q: Under Windows XP system, when you open the Start menu → administrative tools → Computer Management, you find that the right window displays "Unable to access the computer XXXX" When you click Local Users and Groups. The error is: The library is not registered. How can i solve this problem?

A: This failure is caused by a missing or corrupted registry key in the registry hkey_classes_roottypelib{97d25db0-0363-11cf-abc4-02608c9e7553}. Workaround: Locate the users and Group.reg file on the Windows XP installation CD, double-click it, and then click OK to add the complete registry data to the current system's registry.

Note: This method is also suitable for Windows 2000, Windows Server 2003, but you need to import registry data for the same version of your system.
