The mohfilt.sys process is a system driver file that is implemented by Intel chipset drivers and firmware utilities for integrating certain functionalities that are related to modem devices connected to the Windows-based computer. This means Windows-based systems equipped with motherboards that are integrated with these Intel chipsets and modem-related device components use the mohfilt.sys file for communicating with the modem devices connected to these motherboards. The mohfilt.sys process specifically assists these modem devices in implementing its on-hold features into the Windows-based system upon user request. The mohfilt.sys file is bundled into the installer distribution packages of these associated Intel chipset firmware components and device driver software utilities, which means the mohfilt.sys file is placed in the system upon the installation of these Intel firmware resources and drivers.

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

After uninstalling applications it is a good idea to scan you Windows registry for any left over traces of applications. Registry Reviver by ReviverSoft is a great tool for doing this.

A process usually a part of an installed application such as Intel Modem On-Hold Filter Driver Module, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.

We have not received any complaint about this process having higher than normal impact on PC performance. If you have had bad experiences with it please let us know in a comment below and we will investigate it further.

The first thing you should do if mohfilt.sys. is causing errors on your computer is to run a Windows registry scan with Registry Reviver If you are still seeing errors after this you should uninstall the program that mohfilt.sys, belongs to, in this case Intel Modem On-Hold Filter Driver Module
