svchost process using 86% of CPU

[Steve Richter]

Just upgraded to Vista from XP ... system running very slow. In task
manager I see SVCHOST using 86% of the system. Also something called
ALI5289 - AliRAID Application is using 6%. I have two SATA drives
which are mirrored. This all worked fine with XP for the last year.

Been running like this for the last 4 hours. So something is wrong,
right? Does MSFT offer install tech support?

Go to this MS web site and download Process Explorer.
Install it on your Vista PC.

You should be able to see what is running under svchost that is
monopolizing your CPU. Svchost is a parent process for multiple other
processes.

A lot of the time it is an errant Anti-Virus program...

I'm not aware of any A/V product that has services running under svchost.

In Task Manager, go to View/Select Columns. Place a check mark in the PID
(Process Identifier) option. Note the PID of the svchost instance that is
using all of the CPU power.

Go to Start and type command in the Search Bar. Click Command Prompt in
the results.

Type tasklist /svc and press ENTER. (note the space in the command) This
will show a list of all the processes that are running including the PID for
each process. Locate the corresponding PID that is using the CPU power and
you will be able to identify the culprit.

Some instances of svchost will be hosting more than one process.

If you just upgraded from xp ,Then its going to be the indexing service
causing the cpu usage this will last until indexing is done.
