When you install Office XP/2K or one of it’s components, such as FrontPage XP/2K, Microsoft Script Editor, a program called (Mdm.exe) Machine Debug Manager, which is used to provide application debugging is also installed.
Once you restart your machine, MDM creates 2 temp files (every time) in your Windows folder.
For example, the file name may be similar to:
MDM loads itself via the Registry:
View this entry in Msconfig | Startup
Machine Debug Manager c:windowssystemmdm.exe
All Users HKLMSoftwareMicrosoftWindowsCurrentVersionRunServices
Also in Internet Explorer:
Additionally, if the system has Internet Explorer version 5 or later, Mdm.exe can still be configured to start at the startup of WinME/XP or, if the script debugging feature in Internet Explorer is turned on. You can turn off this feature within Internet Explorer.
Now it’s time to go play in the Registry:
Open Regedit and scroll down to the following key:
Note: on restart, don’t forget to delete all the temp files from MDM.
If another application reinstalls Mdm.exe, or if Mdm.exe /Regserver is run on a computer that is running Window ME/XP, Mdm.exe is re-added to the RunServices registry key.
NOTE: Running the Detect and Repair feature within Office XP/2K causes Mdm.exe to be re-registered on the system.
