I have dual boot system with Linux and Win 10, and Linux time is correct, but the Windows is always 3 hours back. when I manually change it, it keeps coming back 3 hours backwards after reset. The windows time service is running and set to automatically start, so that's not the problem. What may be the problem? BIOS?
Make sure you are in the Right Time Zone for your area.
Boot into Setup (Bios) Set the time here. If it looses time in the Bios then the CMOS battery must be changed.
For the record, I had the same problem, it can be very frustrating.
Try to disable changing time zone automatically. Run CMD as admin and copy/paste:
schtasks /Change /TN "Microsoft\Windows\Time Zone\SynchronizeTimeZone" /Disable
sc config tzautoupdate start= disabled
net stop tzautoupdate /y

Re changing cmos battery in laptop. Some laptops are a breeze and some require disassembly. Google your specific laptop with the words disassembly video. This should find a video for your reference.
In some laptops it is not the standard CR2032 battery. Rather it is a little pack that plugs in. Again google will help you determine.
Watch static this time of year. You may also need to buy some special small drivers to assist in the teardown.
