Function of the Windows 32-Bit Message Server

MORE INFORMATION

Msgsrv32.exe is a program that runs invisibly on the Windows desktop and performs several background functions necessary for Windows operation. These functions include:

• Mediate Plug and Play messages among various parts of the operating system.
• Coordinate automatic responses to Setup programs. This includes checking whether a Setup program has improperly overwritten Windows files, and optionally restoring the Windows versions of those files.
• Display the initial logon dialog box if networking is enabled.
• Play the system startup and shutdown sounds.
• Load installable Windows drivers at startup and unload them at shutdown.
• Run the shell program (usually Explorer.exe) and re-run the shell if it fails to respond.
