Todays article is devoted to wide-spread problem that users all over the world worried about. When svchost.exe process uses a lot of memory and processor time it is reason to check what is going on. But mention in Windows Vista or 7 using 50 – 60 megabytes is not something criminal. Vista and 7 are more complex than previous versions and as svchost is an essential process that has a lot of services running under it is normal for it to use 10 – 70 megabytes.

You can fix svchost issues using simple Svchost Fix Wizard tool that will solve your problems in semi-automatic mode:

Very often you can see strange thing when

C:\Windows\System32\svchost.exe -k LocalSystemNetworkRestricted

Svchost.exe Localsystemnetworkrestricted

using process time and RAM. What is this “LocalSystemNetworkRestricted” by the way? is a service host group that includes several services in it. In standard they are:

  • Network Connections Manager
  • Program Compatibility Assistant Service
  • Superfetch Service Host
  • Microsoft Tablet PC Input Service
  • Distributed Link Tracking Client
  • Remote Desktop Services Device Redirector Service
  • Desktop Window Manager
  • Windows Diagnostic Infrastructure
  • Windows WLAN AutoConfig Service DLL
  • Portable Device Enumerator

but after installing different complex applications they can add different third-party services that will “eat” your memory as well. So ho to check what service is using your memory and fix this problem manually? There is a great tool from Sysinternals that is called Process Explorer. You probably have heard about it while searching information about your problem on forums. It looks scary for the beginners but it is really quite simple to use. All you need is to be attentive and careful not to disable essential parts. So here is where you can find download link for Process Explorer:


After running tool, sorting processes by name and going to “s” letter processes here what I see on my PC running Windows 7 32-bit:

list of svchost processes - process explorer

As you can see I have 14 svchost.exe processes running (which is absolutely normal as they run under different service host groups) and 2 processes are using more memory then others (but 26 Mb is excellent)/ f I right-click on one of this processes and choose “Properties” I can see that it belongs to LocalSystemNetworkRestricted host group:

If I go to “Services” I can see all services that use this particular process to run. I my list there are only standard services listed but you can have some additional third-party ones listed.

In case this process using more then 100 Mb of your RAM that is a reason to look deeper into services and disable non-essential services. There is some information about each particular service in the bottom of the window. Sometimes, there only standard system services listed (better don’t disable them) but you still have a problem with svchost.exe “eating” your memory. In this case you can watch carefully what service running under this process and improve situation. For example, if you have Audio and Network related services listed – you can try updating drivers for your sound card and network adapter which can help them working properly.

If you are not sure how to do this or how to use this or that tool we recommend you to use Svchost Fix Wizard, which won’t require any special knowledges from a regular user and will help you to redeem the problem.
