svchost eating the CPU? - "svchost.png" (1/1) uuEncoded 59747 bytes

[Zack Whittaker \(R2 Mentor\)]

Hmm could be a whole number of things - the point of the SvcHost (Generic
Host Process for Win32 Processes) is that, instead of thinking as
svchost.exe as a service, it's more of a shell to house services in... quite
hard to explain. The reason why you get many of them in one go, is so that
instead of having loads of processes, Windows can compact them into "groups"
of services enabling them to run better and more efficiently.

But back to the question... just from looking at your screenshot... Indexing
Services and Windows Search could well be the problem... but not 100% sure.
How much memory do you have in your machine?

Hi Zack, understood all of the rest of the message - I have 2GB of fast
Geil memory on board. This has only come into play since I installed the
ATI beta drivers - or at least become more noticeable then.

Getting close to doing a complete format and reinstall if I can workout how
to avoid extra additions into the boot system, as I already dual boot with
MCE2005.

Unfortunately I can't tell you what it is... try running a Memory
Diagnostics test. Start > All Programs > Accessories > Memory Diagnostic.
See if that helps :o)

I had the same problem.
So I played around with ProcessExplorer ([url]www.sysinternals.com[/url]) and
services.msc.
You have to run ProcessExplorer with admin rights.
With ProcessExplorer, look for the svchost process which eats the CPU,
see what is after "svchost -k", then in services.msc find the services
launched with this argument.
After a few try, it was "SSDP Discovery Service". Stopping it stopped
the CPU-eater process, and performances became a lot better. This
service is used by "Media Center Extender Service" and "UPnP Device
Host".

You'll see mssearch.exe uses a lot of CPU too when it indexes your hard
disks. The service name in services.msc is "Windows Search Service". It
helps faster files searches, but uses a lot of CPU.

Yeh, a lot of services can be disabled... I wrote this some time ago now...
---

Application Experience Lookup Service (Glass goes)
Desktop Windows Manager Session Manager
DFS Replication (if it's a standalone machine)
External memory Devices Management Service
File Replication (as DFS Replication)
Internet Connection Sharing (make sure nobody is sharing your network
connection from your computer though)
Media Center Extender & Reciever & Sheduler & Launcher Service (Media Center
won't work afterwards)
Microsoft iSCSI Initiator Service
Microsoft Software Shadow Copy Provider
Offline Files (no offline networking synchronisation)
Parental Controls (make sure no kiddlywinks are using the machine!)
Protected Storage
Quality Windows Audio Video Experience Service
Remote Registry Service
Smart Card
Smart Card Removal Policy
SSDP Discovery Service
Tablet PC Input Service (don't disable if you have a Tablet PC)
Themes (Windows Classic will kick in, no Glass *at all* but saves loads of
RAM)
Volume Shadow Copy
Windows Colour System
Windows Image Acquisition
Windows Media Player Network Sharing Service
Windows Search Service

Disable at your own risk - but even on mine, I've tried and tested and
noticed not much difference in how things run, but the machine runs faster
on one of my older machines (Vista rating of 2, so it's not bad performance
now!)

Thanks Christophe, but as I'd developed a few other problems as well I
decided to reload this morning,so got up early and manage to get Vista and
office on as well as the MCE/TV system working before work.

Will certainly watch out for those processes though and grab a copy of
sysinternals as it looks like it will be a useful tool for Vista playing:)

Indeed as some of those services are useful :)

Chris, and the problem was there under the new install as well. Disabling
that service resolved the problem perfectly, so my thanks indeed!

My pleasure! Happy that I could help! Now I hope someone will be able
to help me on my network problem, it's posted in the "network" thread
started by Travis King 2 days ago!

Indeed, now running a good 60% of the time under Vista and loving it. :)

Just got to track down what service launches the 'mssfh' process and I'm
happy as when that launches it can eat a good 45-50% of the CPU!

Will take a look at the thread and see what i can find!
