Scvhost.exe Using 75% Of Laptop Physical Memory

» I have recently noticed that scvhost.exe is using up more than 75% of my computers physical memory, and it's slowing my system down. Is there any patch release that will prevent scvhost.exe from using so much Physical memory?

» According to Microsoft: "svchost.exe is a generic host process name for services that run from dynamic-link libraries". Could we have that in english please? Some time ago, Microsoft started moving all of the functionality from internal Windows services into .dll files instead of .exe files. From a programming perspective this makes more sense for reusability… but the problem is that you can’t launch a .dll file directly from Windows, it has to be loaded up from a running executable (.exe). Thus the svchost.exe process was born.

If every single service ran under a single svchost.exe instance, a failure in one might bring down all of Windows… so they are separated out. Those services are organized into logical groups, and then a single svchost.exe instance is created for each group. For instance, one svchost.exe instance runs the 3 services related to the firewall. Another svchost.exe instance might run all the services related to the user interface, and so on.

Sometimes a virus(TrojanDownloader:Win32/Banload.QO) will disguise itself as svchost.exe and eat up a lot of memory, therefore, you have to remove it. But the normal associated exe files can be removed at the same time. Then DLL Suite comes up for help in this case

Click Dashboard menu and > Click Scan DLL Errors button > Click Fix DLL Errors button after the scan. And all the problems directly associated with svchost.exe file are fixed, because of the built-in feature of Fix EXE Virus in the Dashboard menu.

For example, Windows Defender uses a service that is hosted by a svchost.exe process.Svchost.exe is not a malicious program.

    This can also happen if the computer is infected with malware or virus, try to run an online scan and remove any infected items and check if it works.

    I used the command line method to see what services were running and disabled them one at a time. It turns out that Superfetch (SysMain) was the culprit. As soon as I disabled it, my memory usage dropped in half.

  4. KEVIN RYAN replied on February 22, 2013: » I disabled "Windows Audio Endpoint Builder" in services.msc and the problem is gone. That service is controlling audio devices but I have a Realtek sound card and I installed newest drivers for it and the sound & speakers works.

    After I restared, svchost.exe still using much memory but now it's linked with cscservise. Not sure what is going on right now.

    I did some resarch on the Internet and came up with this SuperFetch service. After disabling it in task manager, svchost.exe became normal and it didn't use that much memory. Also, I did disable it in services.msc and I hope it will work as good as it was.
