The winflash.sys process is a system file that is distributed with other SYS driver files, certain modular DLL (Dynamic Link Library) files, specific background processes, some EXE program resources and various components. These are used by the firmware and driver software distributions of certain motherboards that are equipped with BIOS chipsets and devices from Phoenix Technologies. The winflash.sys file is placed in the system alongside these other components upon the installation of these Phoenix BIOS chipset/device firmware distributions and driver software packages. This also means the winflash.sys process is bundled with the installers of these Phoenix BIOS firmware resources and driver software components. The winflash.sys process is specifically deployed as one of the driver file resources of the Phoenix BIOS Flash Menu module, which is an applet built into the firmware and driver software distributions of associated motherboards integrated with BIOS chipsets and devices from Phoenix Technologies.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. winflash.sys. is used by Phoenix BIOS Firmware and Driver Software and Phoenix BIOS Flash Menu Module, If you shut down winflash.sys, it will likely start again at a later time either after you restart your computer or after an application start.

A process usually a part of an installed application such as Phoenix BIOS Firmware and Driver Software and Phoenix BIOS Flash Menu 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.
