Did you know that Windows 8 maintains itself automatically? It’s true. Windows 8 has a new feature that runs maintenance tasks like software updates, security scanning, and other maintenance and diagnostics, automatically. It also runs Disk Optimizer (formerly called “Defrag” ) automatically once every week.
By default, Windows 8 runs automatic daily maintenance tasks at 3AM. If you’re like us and using your computer at that hour :-), Windows 8 is smart enough to wait until you’re done using your computer before running maintenance . Automatic maintenance will wake your computer to do its thing, too.
Windows 8 also gives you the option to change the automatic maintenance time or turn it off all together so, if you wish, you can perform maintenance manually. You can take control of Windows automatic maintenance from the Action Center. You can access the Action Center most easily from the tray icon which looks like a flag, or type Action Center when you are on the Windows desktop – or just type it into the search in the Charms bar.
