The irda.sys process is a SYS driver utility that is used by Microsoft Windows to implement infrared device connectivity functionalities and integrate infrared device compatibility support into the system. The irda.sys file is specifically deployed by Microsoft Windows as a component of the Windows IRDA Protocol Driver module, which is an applet built into widely used versions of Microsoft Windows. The irda.sys file is placed in the system upon the installation and configuration of Microsoft Windows, which also means the irda.sys file is packaged into the installer distributions of various Microsoft Windows OS versions. The irda.sys process works together with some executable application resources, certain DLL (Dynamic Link Library) modules, certain SYS driver utilities, specific background and system process items among other components that are used and referenced by Microsoft Windows whenever it is required to implement infrared device connectivity functionalities and infrared device compatibility support into the system.
