svchost.exe = slow startup (Win 7)

[AVSIC]

I wonder whether it is possible to speed up my OS (Win 7 Pro), that get slowed at the startup, by uninstalling some or most of updates?

FACTS:
It's relatively new OS that I bought together with my laptop. Hardware is not in question (3GB DDR3, Core 2 Due). I monitor my startup software with Winpatrol very accurately I must say.

Nevertheless, it seems that svchost.exe occupies more than 50% of CPU usage at startup that lasts about 10 mins before it starts to decrease percentage.
I found something quite similar to my problem: How to Solve the Svchost.Exe 100% Cpu Utilization Problem - wikiHow

I disabled Windows Updates and uninstalled unneeded ones but I left most of them (Security ones and MS Windows ones) untouched. There was actually no difference in speed, but, I think there is a problem.

So, to remove all updates or some of them or some other solution?
Thank you so much!

hello..
did you sure your computer not detected by virus??

when you type msconfig, going to startup tab..that's the application running on startup n some of the service is run at the time too. you can also disable from there.

Thanks ryo for showing me a new interesting way to monitor what is running!
I am however pretty sure there is no virus or spyware because of a trustful software - BitDefender Total Security 2010.

My question would be: is it safe to uninstall all MS Updates? Or this would not be wise...

 

[ryo]

my laptop, i'm disable the update..because i think n i not need the update.
so when if you not update the path of windows that's could be run too like usually. but you must make sure that's your uninstall is don't change the system of the windows.

It would be too much complicated to ask which updates from the list "should" I remove, but for now I wouldn't do any removing, thank you!
I am interested in one more thing... if ALL MS Updates are removed (including office 2007, security ones for Windows etc.) what would happen?

Do you know for sure which svchost.exe is consuming the CPU on startup? There are many, and each can contain multiple services. Just because *a* svchost.exe is consuming memory doesn't mean you have a windows update problem (besides, that was actually an MSI engine problem, on XP, which was fixed for XPSP2 with a hotfix (and included in XPSP3). The problem should not exist on a Vista or Win7 machine.

sorry for the late reply.. don't remove the security or office 2007,i think you're using office 2007. that's such of program, and i think you need it. right?
so you can choose what the feature or programs that's you're using.

Don't know if you are still keeping up with this, but I would not remove any updates, and leave windows updates as auto or ask you first. They can fix minor problems and help keep out malware (just having an AV is never enough). svchost are your services. A lot of the ones that run automatically can by set to manual and there are a couple that should be turned off for security reasons, like remote registry. You can find list online that tell you which ones can be set to manual or disabled. Be assured that not all can or should be. Also, I disable superfetch. By default it runs at startup and starts loading programs you use a lot. It can help those programs load faster when you actually open them but it can also slow down your PC when you login.

i don't disable all the update, i just configure that by myself,,if i think that's feature or program doesn't use for me..so i custom it.

IMHO it is not wise to remove Windows updates unless you find one that is causing problems with your system. I have never had Windows updates slow down any of my computers. Office 2007 can slow things down if it is started at boot. Using msconfig/start up and turn off Office and see if it starts quicker. If Office is needed at times just put it on your desktop and start it when needed. Using msconfig how many things have check marks; I have 5 every thing else starts when I ask it to. Just because you have programs doesn't mean they have to start at boot. Some time when download a program it will install itself to start at boot weather you want it to or not, so check that also in msconfig.

ryo, that was meant just for the OP, not you. He was considering removing security updates which is a big no-no. I choose which updates to install as well. For some reason Windows updates wanted to install an old version of my graphics card driver. I had to uninstall the driver and reinstall the new one, and reconfigure everything for it.

 

[ryo]

yap..like i said before..use msconfig at startup tab and services. that's can disable from there.
and the other information,some of the windows update is can cause a problem. and i saw many case of it. so that's i mean is you can custom what you want to install the update.

yap i know that.. and i just explain. and congratulation on you 400 post.

Ok...
I have control over many startup programs and would like to ask something about services... For example, there are services related to VMware workstation that are "running". If these ones are stopped, will VMware app load normally when I want to load this program?
Or should I turn them on, and after that, start the program?

P.S. Sorry for the late reply.

 

[ryo]

when you stop the service..then you load the vmware..that would automatically run the service when you run the vmware...but you should try it..

 

[AVSIC]

Thank you!
And how to prevent some services from starting at the startup?

Can this selection be done using msconfig by unchecking services I want to stop permanently?
Thank you once again for your time!

 

[ryo]

yes you can disable it from msconfig. or other ways is from control panel then administrative tools and services.
search what service do you want to disable.

I think it would be better to ask this before, rather than after doing changes:
Can a backup (even done by some program like CCleaner for example) help me returning to completely safer configuration and remove errors I can do by modifying services?
I will still think twice before doing so, but am afraid of making permanent errors that will keep showing even after backup... So, how much backup can help here? cca100%?

Hey, sorry to bump an old thread, however SCVHost is screwing my system. This week I did a fresh install of Windows, one day (like a week ago), my pc started lagging to no end, a simple "minimize" of firefox would take .5 of a second, I know my pc, i knew something was up, so i ran MSE & Malwarebytes... nothing, ran defrag, nothing, i ran ccleaner (registry cleaner), and nothing, after that I thought it was a virus, so i formatted my PC... to this day I still haven't fully restored the pc and it's doing it still... i've been having to leave Windows Task Manager open so I can see when it starts, it shoots up to 90k+ at times... when I went to processes it had the USB enumerator and several other "tasks" i don't recognize. When I see them open I'll take a screenshot and load it up here. I >THINK< it has to do with my Zune 30GB... it seems to act up more when it's plugged in... I'm not sure D:

And, it did it again, as I stated it, here's a screenshot of the issues...
