Service Host: Local system (network restricted) is thrashing hard disk

I am having windows 8.1 with update 1 installed and all release updates of windows till the date i am posting this questions. System is laptop, Core i3 with 6 GB RAM and 500GB hard disk.

When ever i restart my CPU or resume it from hibernate or sleep, "Service Host: Local system (network restricted)" process which i can see in task manager along with many other child services, is taking 100% Hard Disk.

These process makes system very slow not even at startup but sometimes, they drill the hard disk anytime they want.

possible duplicate of Windows 8 hard disk usage 100%

– DavidPostill – 2014-10-23T10:14:04.887

It is not duplicate and even IMPOSSIBLE duplicate because the question you referring as duplicate is discussing the system infected with virus and virtual memory which is thrashing hard disk. I am having 6GB RAM out of which only 2 GB is used and 4GB is still free mean no virtual memory issue. Secondly about virus issue, i am having up to date Kaspersky Anti Virus and scanned the system also. It is clean. – Programmer – 2014-10-23T10:19:11.343

Try this one then Windows 8 disk usage is 100%

no. this is not solving my issue, i have already tried, defrag, cleanup, chkdsk, disk health – Programmer – 2014-10-23T10:31:32.457

@magicandre1981 the post you mentioned is not solved. – Programmer – 2014-10-23T21:25:05.957

look at my comment and provide the trace of the disk usage – magicandre1981 – 2014-10-24T04:03:24.167

have you captured a disk trace? – magicandre1981 – 2014-10-28T05:03:19.767

Still not. Intact I'm having difficulty to do that. Isn't there any easy tool to trace disk? – Programmer – 2014-10-28T08:32:16.183

I think this is very easy. Install the WPT and copy/paste the command into a cmd.exe: http://pastebin.com/AyxAVU60

I really appreciate the help by the user @magicandre1981. Apart from that the solution that i came to have is to disable Superfetch service in Windows. Microsoft says it improves system performance over time by seeing program usage but what i research on the internet, many users complained about it that initially when system is newly installed, it runs ok but within time, Superfetch starts thrashing hard disk.

To experiment it my self, i first stopped this service, then suddenly my hard disk usage dropped from 98 percent to 5 percent. Immediately i found that it was culprit. I disabled this service and when i hibernated system, to my surprise, the hibernate is very fast now. As well as resume was more fast than ever.

The concern that Microsoft says that it improves the performance, what i see that after disabling Superfetch Service, system performance is increase instead of dropping.

Thank you everyone. This was the solution.

The HDD usage comes from the superfetch service which preloads data from the HDD into the RAM:

enter image description here

Starting with Vista this service loads data into the RAM to speedup the performance of Windows. Also starting with Vista, the IO activities also have priorities like processes. And superfetch runs at very low priority. So it should not affect other IO activity, because normal IO activity runs at a high priority.

I can see that you have some 3rd party drivers running, maybe this impacts the HDD performance. Remove them and see what happens.

If this also doesn't speedup the performance, replace the WD Scorpio Black (WDC WD5000BEKT-75KA9T0) HDD with a SSD.

which 3rd party drivers? please tell. i am having issues so i am complaining. It is not minor effect. it is huge effect on performance. really. – Programmer – 2014-10-30T21:33:02.963

look the picture: eubakup.sys and eubkmon.sys. Looks like both are part of EaseUS Todo Backup. – magicandre1981 – 2014-10-31T07:51:56.663

I know they are part of it. So should i disable EaseUS Todo Backup Service name "EaseUS Agent Service"? – Programmer – 2014-10-31T08:38:39.033

EUBKMON.sys is a Windows driver. A driver is a small software program that allows your computer to communicate with hardware or connected devices and EUBakup.sys is an important file process that locates in the Windows\System32\ or folder, it guarantees Windows system's stability and the function of program that require this file process. Both are not EaseUS Todo Backup files. – Programmer – 2014-10-31T08:41:47.867

they are not part of Windows. I don't have them. Remove the backup tool and see if the HDD issue is gone – magicandre1981 – 2014-10-31T08:44:46.667

I got these definitions from internet. Anyways. Anyways, instead of uninstalling EaseUS Todo Backup application (because i use it for the backup tasks), i have disable both of its services named "EaseUS Agent Service" and "Guard Agent Service" – Programmer – 2014-10-31T08:51:15.750

Where did this picture come from? What utility produces it? – Eric – 2016-12-01T02:23:26.723
