BIOS wala check karongi waise is trick se mere 2 warnings ae hain.

Sometime you have to make choices which you otherwise does not make like I switched to Windows 8.1 from 7 because of sheer reason of engery improvements. Electricity tariffs are increasing like boom so if we can save little bit of our bills its worth it.
I am one of the worse offender of Windows 8 and still but just because of low RAM usage and incredible speed improvement and boot speed improvement, I think taking this sour pill worth the risk to upgrade to Windows 8.1.

My Desktop BIOS has HPET enabled and I turned on in Windows 8.1 and also previously when I was using Windows 7.
