Microsoft Microsoft has released patches for 19 vulnerabilities, 14 of which are critical, hitting at holes in Excel, Word, Office, Exchange, Internet Explorer, cryptographic technology and the whopper of them all, the zero-day vulnerability in the DNS Server's use of RPC. The DNS remote code execution vulnerability affects server-grade operating systems, including Windows 2000 and Windows Server 2003, and only those that have the DNS service enabled, such as Domain Controller, DNS Server or Microsoft Small Business Server configurations.

My svchost.exe is taking up 100% of my CPU and it never stops. A look into Process Explorer informs me that it's the automatic update's fault. Killing the process and trying the update via Internet Explorer effects the same result: system grinding to an unusable halt with laptop fans at full power and CPU maxed to 100%, all because of the automatic update.

So I've decided to disable automatic updates once and for all, and I guess I'll never have my Windows installation up-to-date again, short of a complete reinstall (if that were even to work). So much for MS quality engineering... oh wait, that never happened...

Scrapping the XP partititon is looking more and more appealing all the time... Now if I can just find a Linux distro that properly supports my soundcard, I'll be in business. (Ubuntu emits clicks whenever I type certain keys on my keyboard, for no apparent reason.)

Yeah, I recognize that behavior from svchost.exe on my Win2K3 Server. Nothing to do but let it do its work - and hope the updates don't fail ;)

I encountered this one recently. Had just cloned 30 identical computers, booted them up and found that the Windows Update thread was hogging the CPU indefinitely on each one. Had to go round each of them disabling AU (not fun when they are running on <1% CPU).

This is a known issue (something to do with internet access) so there may be a fix available.

I just encountered (and fixed) this one today.

You need to install Windows Update Client 3.0

More info here

Then install Hotfix 927891

Hotfix can be downloaded from

I hope this helps...

Well that seems to have fixed it, more or less. I installed those two things as you said, then tried the update, and while it still resulted in svchost.exe taking over 99% of the CPU, I let it ride its course and it was done in about 20 minutes.

The strange thing is that despite the incredible number of posts I'm able to find via Google on this issue, my search doesn't seem to lead to a useful fix or MS Knowledge Base page (even when I search directly from the MS support site). I'm curious to know where you found out about this method.

Of course, even assuming a user manages to find the magic ingredients to get Windows into this "fixed" state, it still exhibits behavior that's incredibly inappropriate and intrusive for software that's supposed to be running in the background.... I feel sorry for all the many newbie users out there who probably think their computer is simply broken and have no idea how to fix it....

...but at least it worked for now, for me. Thanks for the tip!
