What is superfetch? Its in my Window sTask Manager and it uses up a lot of CPU power ...do i need it and what is it?

The program is placed in my Windows Task Manager and takes up a lot of CPU power, and i am wondering what use can it possibly have? my CPU usage has now constantly been 100% and my antivirus is only using 5%.

'Superfetch' and 'Windows Host services' are taking up so much CPU power on i3, 3 gb Sony Vaio!

Superfetch is a service in Windows that's designed to speed up app launching by preloading certain apps based on your usage patterns. Tune-Up Blog has a nice explanation of what it does.

However, it should not be maxing out your processor all the time. If it is slowing down your computer, you can try to disable it.

To disable:
Open the Start Menu.
Type "services" and hit Enter
Look for Superfetch in the list and right-click it>Properties
Set the startup type to disabled and click the Stop button to stop the service
Click Ok

You also will want to make sure your anti-virus is up-to-date and your computer is clean.
