Shutting computer down while updating
When Windows 7 launched, one of Microsoft's selling points was that it was designed to help your battery last longer.
One of the main features users will actually notice is that the screen dims before... When you use Sleep, your computer goes into a very low-power state that uses just enough power to keep your programs and open files active in your computer’s RAM.
The animations are slick eye-candy, but they do introduce a delay.
You can disable the animations and window transitions will happen instantly, eliminating the delay.
To view your power plan settings, press the Windows key, type Power Plan, click Settings, and press Enter.
However, if you move a lot of files around, you may want to optimize your drives sooner.
As on previous versions of Windows, click the button to see exactly how fragmented your file systems are.
Windows 8 boots faster than previous versions of Windows, has lower memory usage, and has a desktop that feels nice and snappy.
Like all versions of Windows, Windows 8 has a variety of settings you can tweak to speed things up and make it even faster.
