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

Hey, we seem to have reached the same conclusion: that it's Windows Update. In my post below I explained how I came to suspect that. Still haven't taken action on it, my discovery being only a few minutes old.

But the solution really seems to be to take Updates as seriously as one takes paying bills on time every month, manually.

I have windows 10 and the same issue

i am gonna die

new laptop, i5

Switch off your Windows update completely.

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.

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.

Hope the above information helps.

Do get back to us and let us know the status of the issue by your next post or in case you need further assistance.

Or maybe we can put it in this way of theory...

Someone is getting the data out from MY computer. along with  Service Host: Local System (Network Restricted 8-7-10 etc...) other closed apps begins to run out of nowhere. Lets not forget Service host also had Data sharing in its details. When I stopped Data Sharing "Host process for settings synchronization" started to run. Microsoft Office suite began to run *I had it completely down* "YET" *IT RAN* WITH some data bla bla written in it(I don't reckon the program clearly*. Huh, now something else is running.

before you say me bout viruses... I know how to use a PC, from head to 'knee'. I've been cautious about viruses and didnt install any services lately. browse from trusted place, visited "trusted sites" including microsoft.com.

Can I get an insight on how to completely stop anonymous data from passing on? ah yea, I did stop every known app and software from sending usage stats to its maker.
