Windows 10: showing seconds in the system tray clock

README.md

Showing seconds in the system tray clock in Windows 10 is accomplished via a registry hack. It is based a boolean DWORD entry called ShowSecondsInSystemClock. The entry doesn't exist by default, so must created by hand, or you can use the code below to create two convenient registry script files, one for enabling seconds and another for disabling.

Remove Seconds From System Clock.reg
