A process called Service Host: Local System is using up all of my laptops resources

My laptop has been running very slowly for the past few days which is weird because my laptop is quite powerful and has always run very fast. I looked at my task manager and saw that a process called Service Host: Local System was using up almost all of my RAM. I am running Windows 8 Pro on a Sony VAIO S13P. What can I do to fix this problem?

Hi Bharat_47.

 

I am glad to know that you posted query in Microsoft communities.

 

From your description I can understand that your computer is running slow.

 

I need to ask you a few questions in order to assist you in a better way.

 

1. Have you install any recent Windows updates on your computer?

2. Have you made any software changes to the computer prior to this issue?

3. What is the name of Antivirus program installed on your computer?

 

Could you please try the following methods to resolve the issue.

 

Method 1:

Run a system file checker scan check if that helps.

Refer the following steps to run SFC scan.


a) Move the mouse pointer to bottom left of the screen where you see preview of start menu and Right-click to bring up a list of Windows settings.
b) Click on ‘Command Prompt (Admin)’ to bring up elevated command prompt. Note: Click ‘Yes’ if it prompts for permission.
c) In the command prompt type in the following command:‘sfc /scannow’ and hit enter.

 

Method 2: I would suggest you to perform clean boot and check if any third party application is causing the conflict. Please follow the instruction mention in link below and check.

http://support.microsoft.com/kb/929135.

Note: After you have finished troubleshooting, follow these steps to boot to normal startup.
a) Press the ‘Windows + R’ key on the keyboard.
b) In the ‘Run’ windows type ’MSCONFIG’ and click ‘Ok’.
c) On the ‘General’ tab, click the ‘Normal Startup’ option, and then click ‘OK’.
d) When you are prompted to restart the computer, click ‘Restart’

 

Method 3: I would suggest you to perform a virus scan on your computer.

 

Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.

Please follow the link mentioned below.

I have a similar issue but the same process seems to only use a ridiculous amouunt of hard drive usage speed and time at times.  It doesn't happen all the time but frequently, often after resume from sleep it does.  I'm running windows 8 pro on an Asus s505c.  

It does really look to me like the process is part of windows and I therefore ask what it might be doing.  Thanks

same problem also win8 and HP Envy m6 with A10. Not the fastest computer but I was pleased when I got it. Lately though it is slow. Using Kaspersky internet security. Scan shows no infection (but I know that doesn't always mean it is virus free) I have only had this computer 2 months. I checked my task manager and noticed that service host: local system is using over 70MB of memory third behind internet explorer and Kaspersky. just curious if this is a legit program and what it is for. it is not my CPU (that stays below 5% -10% even when running slowly. )

I want to report a similar problem also, except in my case it is using up my cpu resources. My laptop is pretty fast however this set of services (UPnP Device Host, Time Broker, SSDP Discovery and Function Discovery Resource Publication) all under the Service Host: Local Service (No Impersonation) (4), uses up 64 percent of my CPU. I first realize this problem because i could hear my fan running at really high speed even when all my apps were closed.

This issue only started recently in the past month and though I cannot pinpoint the exact date, I can saw that I did install the latest MS updates for windows 8 in the last month. Also it seems to do this whenever I run an internet app (can't say for sure) but even after the app is close it continues to run until i manually stop the service.

Btw: I have a Dell SXPS w/ Window 8 pro (manually installed)

Something to note - I was experiencing a similar issue (CPU usage from service host was over 70%), but I noticed the process below it was an HP help process. I ended that, and my service host usage immediately dropped to 0%. Try closing superfluous HP processes and see if it does the trick.

Thanks for your advice, the CPU usage dropped to zero as you said so. =)

I had the same problem... for me it was Dragon Naturally Speaking, uninstalled it and everything went back to normal... it might not have been the program itself but im thinking the service it was using to check for updates or something
