Windows 7: Svchost.exe High memory usage at startup

I too have this problem, but I just kill the process with no real detrimental effect taking place afterward and move on. Otherwise, it takes 10-15 minutes to finish on it's own while the machine is rendered almost useless (i.e. slow interactive response)

Welcome to the forum.

Terminating an instance of svchost.exe (or any system process for that matter) is asking for trouble. It may work in specific cases but this is by no means a recommended procedure.

Svchost.exe High memory usage at startup

Hello folks:

I too am having this same issue and am looking for a technical explanation. I've contacted Microsoft and they seem as dumb as rocks on the issue, no surprise there!

When W7 starts there is an instance of svchost.exe consuming anywhere from 550mb to 700mb RAM. It is directly tied to about a dozen services all related to "netsrvc."

Any technical advice or comment will be appreciated. Happy Holidays and best wishes for a great 2015!

What is the concern with 550 MB of ram.
Their are more things than can be posted where Windows 7 uses that small amount of ram.
You can chase that small amount of ram around on your system forever and accomplish nothing.

Let Windows 7 worry about when and where to use the ram.

Layback Bear huh?

Sounds more like bear writing than anybody "Laid Back". If YOU wasted YOUR time responding to my post don't flame me!

FYI BEAR - Before I added more RAM recently, this process was using close to 90% of available and taking sometimes 20 minutes to drop back to 30%, it slowed my usage way down.

To sum up, , don't respond if you don't have anything worthwhile to add or contribute!

Robert

PS - If I trusted W7 to do anything RIGHT, I'd not need this forum!

A simple means to cope with this problem ! It works really well

Hello!

I had the same issue and I put a little time to solve it.
The svchost service in question is a Windows service host that contains lots of services, it must be done so that you get into it ... Like you, for almost 10 minutes after the computer has started, I couldn't do almost anything...
Then I get the idea "services.msc" (you type that in the Run bar) : there are there full of services that consume a max of memory and are not necessarily always helpful, it depends on your use your desktop.
The main culprit turns out to be the Windows Update service and its two acolytes : the Security Center service and the Windows Modules Installer.

If you have a correct antivirus, you do not need to search for the Windows updates at each startup.
Personally, since I disabled all three services, I haven't the problem at all any more ; I just reactivate the Update service once a month, at night.

Here's the trick :
- In the Window's path (type set path in a prompt window), create a command file "wud.cmd" (wud like Windows UpDate but you can choose any other name) containing the following code:

@echo off
rem script to activate/desactivate WUpdate services
if "%1"=="" (
echo Security Center service activation :
sc config wscsvc start= demand
sc start wscsvc
echo Windows' modules Installation Program service activation :
sc config TrustedInstaller start= demand
sc start TrustedInstaller
echo Windows Update service activation
sc config wuauserv start= demand
sc start wuauserv
call :verif
call :verif
) else (
echo Windows Update service desactivation
sc stop wuauserv
echo Windows' module's installation Program desactivation
sc stop TrustedInstaller
echo Security center service desactivation
sc stop wscsvc
call :verif
call :verif
sc config wuauserv start= disabled
sc config TrustedInstaller start= disabled
sc config wscsvc start= disabled
)
pause
goto :eof
:verif
timeout /T 10
sc query wuauserv
sc query TrustedInstaller
sc query wscsvc
goto :eof

Here it is !

- Now you just need to open a command prompt window as administrator and to type:

wud d

(d like disable)

And it's good! The concerned services are disabled and let you easy.

- Then, every month, in a command prompt as administrator, type "wud" without any argument. This reactivates Windows Update service, and allows you to make updates. If necessary, schedule a task to remind you.

What a relief, I was also wondering how to get out but this little trick is enough and tested OK !

Regards,

Guilyou

* to open a prompt window as administrator, just go into the file "All programs" of the main menu, select "Accessories", then right click on Command prompt -> Run as administrator
You may also, for future usage, right-click on the command prompt icon in the taskbar and attach it to this taskbar (then you just have to rightclick directly on it to open as an administrator).

I've been having this problem off and on for the past few days. I did exactly what WHS recommended and then highlighted "wuauserv" Windows Update and pressed stop. svchost.exe went from 350 MB down to 48 MB. It had been at 1 GB, but I guess it caught scent of me on its trail and tried to shape up before I hunted it down. Too late. I'm on to you now Windows Update.

I had a similar problem, although my laptop became unresponsive about 10 to 15 mins after start up.

Having arrived at this thread and installed Process explorer, thanks goes to WHS, I could see that my memory usage went up massively due to svchost(netsvcs) kicking in.

The solution was to use Process explorer, right click on svchost(netsvcs) and lower the priority to:

Background: 4 (Low I/O and Memory Priority)

My laptop is now running smoothly again.
