  • Hi,

    I have had the same issue and I was able to resolve it.By default the startup type for i8042prt.sys at boot time is set to enabled.
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt > The REG_DWORD entry "START" is set to "1" which means enabled.

    The driver is not installed by default and it is stored some directories.In example :

    The driver can only be loaded if it is under stored under system32\DRIVERS\i8042prt.sys.

    If you never plug-in a PS/2 keyboard to your PC it is never copied to the system32\DRIVERS folder and you will see everytime this event if you start your PC.

    The solution is either you should plug-in a PS/2 keyboard one time or you should change the value of the "START" registry entry to "0" which means "disable" at startup or "do not try to load"

    Thats it !

    Hope it helps.

    Best regards,

  • Hello,

    Cengiz' answer was almost perfect, except for the actual registry value you set the value to force "DISABLED"; thus preventing its startup.

    The Registry value for "Start" in the HKLM\System\CurrentControlSet\Services\<ServiceName> Key should be set to a Decimal value of 4 for disabled.

    See this KB for Reference:

    (excerpt from the above KB Link)

    Start     REG_DWORD     Start constant
    Specifies the starting values for the service as follows:


    0x0            Kernel     Represents a part of the
    (Boot)                    driver stack for the boot
                              (startup) volume and must
                              therefore be loaded by the
                              Boot Loader.

    0x1            I/O        Represents a driver to be loaded
    (System)       subsystem  at Kernel initialization.

    0x2            Service    To be loaded or started
    (Auto load)    Control    automatically for all startups,
                   Manager    regardless of service type.

    0x3            Service    Available, regardless of type,
    (Load on       Control    but will not be started until
    demand)        Manager    the user starts it (for example,
                              by using the Devices icon in
                              Control Panel).

    0x4            Service    NOT TO BE STARTED UNDER ANY
    (disabled)     Control    CONDITIONS.
