= Service Host, and any one instance of svchost my be providing several different Services. It is likely that there is one particular Service that is the culprit. Sysinternals free Process Explorer will help you discover which Service it is: http://technet.micro...s/bb896653.aspx
Once up and running (no install required) Process Explorer will display the Services hosted by each svchost
in a tooltip by holding the mouse over the process entry. You can then alter the function of the Services one-at-a-time to discover which is at fault.
Please do a little reading before making changes to XP Services.

These 2 sites offer solid info on XP Services:
Black Viper (for SP3): http://www.blackvipe.../servicecfg.htm
Black Viper (for SP2): http://www.blackvipe.../servicecfg.htm

Black Viper is a little more aggressive, The Elder Geek a little more conservative.

To access 'Services" in XP, open a Run box from the Start Menu and type: services.msc.
Scroll down to the Service you want to control and double click it. In the dialog box that opens, use the small central drop-down menu to select the setting you want to apply to the Service:Automatic
- the Service starts with Windows and runs continuously.Manual
- The Service does not start with Windows, but is available to start by the system or user if required.Disabled
- The Service will not function under any conditions.
It should be clear that only Services clearly known
to be un-needed should be disabled. Manual
is a "safe" setting. Please do make changes to Services one-at-a-time to make it possible to identify the cause of any problems that may result.
Beyond the svchost
issue, there are several things that can be done to improve the performance of a slow system.
I formerly ran XP on a 750 processor with only 128 RAM.
I found that marking the System Performance Settings for best performance gave the biggest boost. Sure it looked like '98, but it ran better. I also set the Page File (Virtual Memory) to "System managed size" and left plenty of room on the hard drive for it. Dropping themes,wallpaper, and system sounds helped as well. I turned off the Screensaver, and ran all updates (including Windows) manually to cut down on background processes.
Beyond that, I got into the practice of doing just one thing at a time. If I wasn't willing to close a window, I at least minimized it to take a load off explorer.
XP is quite robust, and, on a more powerful system, full of nifty special effects. With my limited system resources, I found that I valued performance and reliability over eye candy and "conveniences." Perhaps you will as well.
