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.

    I have a $2000 gaming pc running on an overclock, and it was ramping my cpu to 65%...  Idk what you consider "high end", but i promise you the majority of microsoft users are not running even a quarter of the power i have.

     That said, i also dont think the program itself is a bad idea.  Until tonight i had no issues with it.  suddenly an update drops and the service became bugged.  Just one of many kinks not yet worked out on windows 10

    this service made my computer almost useless.  It took expert techs 3 days to figure out the cause.  To me it is a virus or malware of the worse kind.  I recommend stopping it or better still MS should quit installing in on computers.

    I have HIGH END GAMING/DESIGNERS SYSTEM -- I have 64 gigs of RAM and I am running an i-core7.  The hardware cost of my system is over $5k.  I get very technical with what I expect my machine to do. 

    And yes, I agree that very few people have the power that we have.  This program has glitches on WINDOWS 10 PRO 64bit (OS).  Please remedy it !!! 

    Thank you.

    Respectfully,

    KBroz
