Remotely Edit the Windows Registry

1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. On the Registry menu, click Connect Network Registry.
3. In the Computer name box, type the name of the remote computer, and then click OK.

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}

5. On the Registry menu, click Export Registry File.

10. Quit Registry Editor.
11. Restart the remote computer.

Edit the Windows Registry from a Parallel Installation

If you are unable to remotely edit the Windows registry, you must install a new copy of Windows 2000 into a new folder and then edit the registry of the original Windows installation. To do this, follow these steps:

1. Install Windows 2000 to a different folder. For additional information about how to install Windows to a new folder, click the following article number to view the article in the Microsoft Knowledge Base:

   266465 How to perform a parallel installation of Windows 2000 or Windows Server 2003

2. Log on to the new Windows installation.
3. Click Start, and then click Run.
4. In the Open box, type regedt32, and then click OK.
5. Select the HKEY_LOCAL_MACHINE on Local Machine window, and then click the following registry subkey:

   HKEY_LOCAL_MACHINE

6. On the Registry menu, click Load Hive.
7. Navigate to the System file in the original Windows 2000 installation location.
   
   By default, the System file is stored in the following location:

   %SystemRoot%\System32\Config

8. Click Open, type an arbitrary name in the Key Name box, and then click OK.
   
   The original HKEY_LOCAL_MACHINE hive is loaded as a subkey of the current key.
9. In the arbitrary name key (where arbitrary name is the name that you assigned to the HKEY_LOCAL_MACHINE registry key from the original Windows installation), browse to the following registry subkey:

   ControlSet001\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}

10. In the right pane of the Registry Editor window, click the following value:

    UpperFilters: REG_MULTI_SZ: aw_hostkbdclass...

11. On the Edit menu that appears, delete only aw_host. Ensure that kbdclass remains.
12. In the warning message dialog box that appears, click Yes.
13. Double-click the minus sign (-) to collapse the HKEY_LOCAL_MACHINE registry subkey.
14. On the Registry menu, click Unload Hive. Click Yes to confirm the operation.
15. On the Registry menu, click Exit.
16. Restart the computer, and then select the original Windows 2000 installation on the Startup menu.
