Helping people with computers... one answer at a time.

When reporting a failure it's important to include all the relevant information. We'll outline some of the basics that help get your question answered.

I keep getting SVCHOST failures. Why?

I'm seeing a questions about svchost failures come by on the Ask Leo! web log on a regular basis. Unfortunately most of the questions are just about that detailed often without even including the message text. So I'll cover here what a good error report looks like and then include a few steps that may start to help identify the cause of some of these svchost related failures.

In order for any technical support resource to assist you with a problem there are a number of standard bits of information that you should just always provide up-front. Most are easy and if you don't supply those they're just going to ask you for them anyway. Why not speed up the process a little by providing these details from the very beginning:

  • The operating system you're running, and its version.

  • The machine brand, its processor speed and the amount of memory it has.

  • Any hardware add-on devices that you think might be related to the problem you're seeing.

  • Whether or not you are running a firewall, a virus scanner, or a spyware scanner, and what brand and version of each.

  • The exact text of the error message, if any that you are seeing. I know this can be a little bit of a pain, but the exact error can convey a lot of information. And trust me, this more than anything else, will be the first thing that your technical support person will ask about. (I've got a few tips on capturing those messages here.)

  • If the problem is reproducible a summary of how to make it happen.

  • A list of any changes that either happened or that you perhaps made to your computer around the time that the problem started; particularly any software or hardware that you installed or setup.

Now, on to svchost. Svchost is particularly hard fella to diagnose because as I outlined in a prior article there are typically several copies of svchost running at the same time.

In addition to the information above I would collect the following to begin diagnosing a svchost related problem:

Any change in behavior after the failure. Does something stop working once you've experienced the error message referencing svchost and if so what?

Capture the output of "tasklist /svc" if at all possible after rebooting but sometime before the svchost related failure. Then after the failure run "tasklist /svc" again and see what if anything is different.

That's not meant to be a solution but a starting point. That information might be enough to help you understand what's failing. If not it's valuable information for the technical support person you'll be talking to.

When I start up my computer, the background freezes up and it takes a while to unfreeze. Then it shows an error message that says there was a problem with svchost.exe. The program had a virus before and I think my virus scan deleted it. How do I restore or fix the file? If it helps, I am running Windows XP on a Dimension 4550 computer.

My recommendation is to read the article referenced in the previous comment, and then make sure your virus checking software has an up-to-date database and re-run. Some viruses are hard to clean, and depending on which, several virus software manufacurers have specific clean-up tools. I tend to visit Symantec ( ) they've proven to have very reliable information.

Good luck!

That's almost certainly a virus. Check out the article and subsequent comments here:

I tried every program that you mentioned in your article and I still have the error message at the start of WindowsXP. 'Windows cannot find C:\windows\svchost.exe. Make sure you typed the name correctly, and then try again. To search for a file, check the Start button, and then check Search.'

Any suggestions?

Sounds like something has added that to your startup. Have a look at this article and see if there's a startup entry for that you can remove:
