Alternative to local APIC timer in Windows 10 ?

[DrkWbl]

Our application is using the local APIC timer for sending interrupts to the CPU in fixed time intervals (about every 1 ms).

My recent research has shown me that in Windows 10 the local APIC timer cannot be used anymore as it is solely used by Windows 10.

(In Windows 7 we have been able to deactivate all processes which were using the timer.)

Is there be any chance a timer which can be configured without using Windows APIs, which is sending interrupts to the CPU and which is not used by any other process?

Thanks a lot.

Best regards
