If you get this error:

= = = = = = = = = = = = = = = = = = = = = = = = =
svchost.exe - application error
The instruction at "0x745f2780" referenced memory at "0x00000000". The memory could not be "read".
= = = = = = = = = = = = = = = = = = = = = = = = =

And also a error dialog about "Generic Host process for Win32 services", then this may resolve the problem:

One of these updates is the cause

These were:

Root Certificate
KB905474 Genuine Advantage
KB890830 April Malware Scanner

open in Safe Mode, choose NO and do a System Restore prior to these updates.

Hope this helps.

If it does not help try this:

1. Boot into safe mode with Network
2. Disable automatic updates in Windows
3. Reboot system into normal mode
4. Do a manual Windows update
5. Enable automatic updates in Windows
4. Reboot once again

What? You lost me. Start again?

Does this relate to my issue? SVCHOST.EXE sending out ARP packets to unknowns?

I did not reply to your message, this was a new post and is FYI only.

I will explain, Windows XP updates caused a SVCHOST error after they installed themselves and the machine rebooted.

ohh ok. Is it just a pop up error? Like svchost has caused a problem with bla bla.

Something like that?

Yeh, a whole bunch of numbers etc. Microsoft is obviously not checking their updates very well

First there was the ANI update and Realtek Control Panel and now this, all in the space of two weeks.

I can hardly wait until "patch Tuesday" in May.

Good luck with your problem.

Looks like an XP update messed things up.

Hope this help if you get this problem.

Hum, had 5 of them messages this week. +users of those PCs complaining they're incredibly slow. Thanks !
Though next time be more clearer with your first post

Edited the first post, I was in a hurry that day

Thanks for the comment, justified.

Our school district has had many of these. While I have been unable to find word one about it on Microsoft's site, I did find this article:

http://www.kb.ucla.edu/articles/svchostexe...plication-error

This article includes a longer version of the fix which almost always works (the short, easy fix above is not always succesful). I've only had to reformat and reinstall one stubborn machine so far.
