On a side note, there are laptops and MBs such as my DFI 790FX that will show a sleep resume bug under W10 when HPET is enabled on bios (a peculiar BSOD that can be identified later with bluescreenview, but at the time it crashes on resume no image on monitor will show), but only when the system clock isn't forced to it. For some reason, IIRC previously W8.1 and early W10 builds were automatically set to HPETs 14.3Mhz instead of the default 3.xMHz on that particular MB without me touching anything (while it didn't on my Asus 890GX that behaves fine on either setting). But since 1607, I must set bcdedit /set useplatformclock true if I wish to be able to resume from S3 (S1 is OK) at default HTT, but it'll still fail at my daily HTT 240MHz setting no matter what.
