Installation notes for Windows 8.1 Pro workstation.


Since we prefer to set the RTC to UTC but Windows expects the RTC to be localtime, create/set the following registry entry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\RealTimeIsUniversal -> DWORD 0x01

After saving the changes, right click the clock on the taskbar and select “Adjust date/time”. On the “Internet Time” tab, disable NTP. The RTC can now be set to UTC and Windows will both correctly interpret it and avoid changing it.
