My windows 10 always resets my time zone to the Pacific while I am here in the central time zone.
I have manually changed the time zone using several different ways using "tzutil /s "Central Standard Time". This only works when I left the "set time zone automatically" option to Off position.
However, whenever I switched to "set time zone automatically" option on and reboot the computer, it always goes back to the Pacific time zone again.
It looks like somewhere in my computer or account, my location is set somewhere in Seattle (I can see that in Windows Maps application)
