Use the Microsoft Register Server, Regsvr32.exe, to remove unnecessary keys from the Windows Registry.

Regsvr32.exe is set up in your Windows System folder by Microsoft Internet Explorer version 3.01 or later. You can also obtain a stand-alone copy of the file from Microsoft's download services. For information about downloading Regsvr32.exe, please see the following article in the Microsoft Knowledge Base:

Follow these steps to remove the Registry keys:

In Microsoft Windows 95 or Microsoft Windows NT 4.0, click the Start button on the Taskbar, and then click Run.

In Microsoft Windows NT 3.51, start Program Manager or File Manager, and then click Run on the File menu.

Type a command to unregister the drivers you want to remove, and then press ENTER. The /u command-line switch for Regsvr32.exe unregisters the driver. The following table shows each driver and the command to unregister the driver. Substitute the path and file name for Regsvr32.exe and the driver DLL file on your computer, both of which are in your Windows System folder by default.

NOTE: In the following commands, an underscore (_) at the end of a line is used as a line-continuation character. Remove the underscore from the end of the line, and type the command on a single line.
