Internet Time Synchronizing
This is a feature that I’ve wanted all along, though I never really noticed. Windows will now automatically update your time via the Internet, using the Network Time Protocol (NTP). You can even run your own time server on a network (using third-party tools) and have all of your computers sync to that one.
The settings are accessed by double-clicking on the time on the taskbar, and switching to the “Internet Time” tab. Windows will use time.windows.com by default, though you can change this to whichever time server you prefer. You can disable the whole thing altogether, but for some reason you can’t change the default interval of two weeks – motherboards with badly drifting clocks may need to be updated more often, and there’s an “Update Now” button just for that.
There are a variety of shareware and freeware programs that will do this for you, and are much more configurable. If you want to see a list of these, you can try visiting
