The i8042prt.sys (the system file name for the PS/2 port driver) is a legacy, low-level input driver that handles communication between a motherboard’s PS/2 controller and the operating system. Unlike USB keyboards, which rely on the HID (Human Interface Device) stack, PS/2 devices use direct interrupts (IRQ 1 for keyboards). The standard driver acts as a translator, converting raw scan codes from the keyboard into virtual-key codes that Windows 11 can understand.
