The vmm.sys process is a system file bundled with other SYS driver files, certain DLL modules, various EXE program components, some background processes and associated resources that are required by the Microsoft Virtual Server software, which is an application classified as a network system virtualization program. The vmm.sys process is embedded in the Microsoft Virtual Server software, which also means the vmm.sys file is implemented into the system upon the installation and configuration of the Microsoft Virtual Server application in the Windows system. The vmm.sys file is deployed as among the SYS driver components of certain modules that are built into the Microsoft Virtual Server software. This means the vmm.sys file is referenced by the system and the Microsoft Virtual Server program whenever the user or the system needs to integrate certain functionalities available from the modules and program components of the Microsoft Virtual Server software. Specifically, the vmm.sys process is deployed as a resource file of the Virtual Machine Monitor module of the Microsoft Virtual Server application.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. vmm.sys. is used by Microsoft Virtual Server and Virtual Machine Monitor Module, If you shut down vmm.sys, it will likely start again at a later time either after you restart your computer or after an application start. To stop vmm.sys, permanently you need to uninstall the application that runs this process which in this case is Microsoft Virtual Server and Virtual Machine Monitor Module, from your system.
