Windows Update / Microsoft Update / svchost / Autoupdate / 100% CPU
We run a domain with about 500 PC's. We've been having a lot of
problems with svchost crashes or 100% CPU usage related to automatic updates lately. We have done a lot of experimenting and poking around on newsgroups, and seen many many different posted 'workarounds', etc None of them seem to work 100%. We've boiled down the workarounds to a script that looks like this: net stop wuauserv net stop BITS move c:\windows\SoftwareDistribution c:\windows\SDOld REGSVR32 /s WUAPI.DLL REGSVR32 /s WUAUENG.DLL REGSVR32 /s WUAUENG1.DLL REGSVR32 /s ATL.DLL REGSVR32 /s WUCLTUI.DLL REGSVR32 /s WUPS.DLL REGSVR32 /s WUPS2.DLL REGSVR32 /s WUWEB.DLL I:\fixes\svchost\WindowsXP-KB927891-v2-x86-ENU.exe /quiet /norestart and then we manually restart. And this works great... **As Long** as you don't resetup/reconfigure Microsoft Update. As soon as you reenable it, wham, your right back where you started with 100% CPU usage. Microsoft Update finally came back with the results on my machine after close to 20 minutes on a Xeon 3.06 Ghz machine with 4 gigs of ram. It's not a virus, malwar, spyware, etc. It is replicateable on machines, vmware sessions, fresh builds, old machines, etc. We have applied the KB927891 hotfix(read the script above) with no effect. We run Windows XP SP2, Office 2003(some 2007), SMS Client, and a host of default other applications and the effect seems to be widespread. Windows Update works fine after the above script, but we would like to be able to use Microsoft Update to keep Office, etc up to date. Does anyone know if there is a fix for this out yet, in the works, anything? If not does anybody know how to unregister Microsoft Update from a command line, is it a DLL that can be unregistered? Going to the update site to turn it off individually on 500 machines doesn't sound like fun. Thanks, Pat |

Windows Update / Microsoft Update / svchost / Autoupdate / 100% CPU
Install this fix for now:
http://support.microsoft.com/kb/927891/ This fixes the crashes and improves performance for somewhat faster scans, and improves the 100% CPU issue in some cases. Still working on the full final solution. This fix replaces kb/932494 and kb/916089 for a cumulative fix for all three issues. "PA Bear" wrote in message ...

Windows Update / Microsoft Update / svchost / Autoupdate / 100%CPU
This what launches MU from the Start Menu, Patrick :
D:\WINDOWS\system32\rundll32.exe D:\WINDOWS\system32\muweb.dll,LaunchMUSite Perhaps unregistering muweb.dll and reregistering wuweb.dll would do the trick, although reregistering may not be need for the wu .dll. I'm not totally convinced that this is correct though ... YMMV On the other hand, why isn't WSUS being used to pull the updates down and then push them out to the workstations ?

Windows Update / Microsoft Update / svchost / Autoupdate / 100% CPU
Yep, sorry. This fixes all the known crashes and does some perf
improvements. There is a corresponding fix "coming soon" in another component that will fix the "hung UI" issue. It's not the 100% CPU that is the underlying problem, it is that the UI threads get blocked and the system appears to hang. "PA Bear" wrote in message ... You may have missed...
