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.

    Superfetch should not be consuming much if any CPU or RAM and if it is there is something else wrong.  If you simply disable Superfetch there will still be something else wrong.

    Disabling an important Windows Service should not count as troubleshooting or fixing anything.  It merely fixes the symptom of the problem and does not fix the real problem.  Apparently that counts as a "solution" to some.

    The SuperFetch Service is hosted by one of the svchost Processes you see in Task Manager and should not appear in Task Manager as a separate Process unless something is very wrong or you have made some adjustments to your system in a misguided effort to improve performance.

    The only way to really see what SuperFetch is doing (for CPU) is to find it in Resource Monitor and it should be doing absolutely nothing most of the time:

    Nobody except you knows what "update dropped" means and nobody but you knows what "the service became bugged" means.

    You say you have "issue" with it but don't say what the issue is.

    I disabled mine and everything loads faster now and no more 100% cpu usage for 30 min when i restart my pc so dont agree with your post. I now never get over 45% usage on start up and  my pc has not run this good since windows 7. Ten is a resource hawg and this fixed it!

    Turning Superfetch off solves the problem until it I restart. Then it turns itself back on and CPU goes to 99%.  How do I permanently eliminate this useless service?

    How many other unnecessary services are in the most recent update and how do I eliminate them?

    Actually its very helpful for those with higher end cpu's and some half good ram. For those with lower end pc's its terrible, but they should do a hardware test on install to determine if it should be active. Removing it would hurt all the people with good pc's.
