The APIC timer had its initial acceptance woes. A Microsoft document from 2002 (which advocated for the adoption of High Precision Event Timer instead) criticized the LAPIC timer for having "poor resolution" and stating that "the clocks silicon is sometimes very buggy". Nevertheless, the APIC timer is used for example by Windows 7 when profiling is enabled, and by Windows 8 in all circumstances. (Before Windows 8 claimed exclusive rights to this timer, it was also used by some programs like CPU-Z.) Under Microsoft Windows the APIC timer is not a shareable resource.
