MDM.EXE................

Mdm.exe is the Machine Debug Manager, which is used by the Windows NT Option Pack and Microsoft Developer Studio to provide application debugging. When Script Debugging is enabled for Internet Explorer 4.0, the debug manager is initialized whenever Internet Explorer 4.0 is started. The Machine Debug Manager runs as a service and is loaded when your computer starts. If you do not use your computer for debugging purposes, you can safely turn off the Machine Debug Manager

How to Turn Off the Machine Debug Manager:

If you run Microsoft Internet Explorer 5 or later, you can turn off the Machine Debug Manager by turning off script debugging. To do this, follow these steps:

1. Open Internet Explorer.

2. On the Tools menu, click Internet Options.

3. Click the Advanced tab.

4. Click to select the Disable script debugging check box, and then click OK.

5. Close Internet Explorer.

6. If you run Microsoft Windows 98 or Microsoft Windows Millennium Edition (Me), delete the registry value that starts the Machine Debug Manager. To do this, follow these steps.

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.
