My system clock (which I can modify in UEFI) is working OK, but three hours behind me. It's always UTC+00, and changing it is useless because it often resets when my notebook runs out of battery.

I just want to know how I can make Windows 8.1 STOP syncing with it each boot?

I pressed Win+I, gone to Metro-UI settings and disabled "Set time automatically" setting but it still does it.

I also disabled the "synchronize time over internets" setting but still no effect. Can I change something in the registry to fix it?

  • If your system clock is wrong, and keeps getting reset when your battery dies, wouldn't you want to have network time synchronization? Otherwise your clock is always wrong, isn't it? – Xen2050 Jan 10 '15 at 2:33
  • @Xen2050 I'll tell you why: 1)because I spend a lot of time offline 2) because even if I haven't it just doesnt work automatically! To sync it I have to EACH time go to the internet_time_sync tab in the settings and press update now! – mekkanizer Jan 10 '15 at 4:19
  • wouldn't the fix be to get a new CMOS battery? – Tetsujin Jan 10 '15 at 11:41
  • @Tetsujin Why spend money on something I don't need at all? I don't want to void warranty (by doing it myself) and I'm not going to pay some cunning a-holes $100 for doing that with replacing the seal. – mekkanizer Jan 12 '15 at 6:36
