1 edit | [XP Pro] Wuaueng.dll / Svchost.exe 100% Usage Problem. Microsoft have an obvious problem with their windows update site. Here's what Ive been seeing. On computer that have Service Pack 3 install, if the users goes and tries to do any windows updates, the website wants to install an update to the updater service which does the following.
The Service pack 3 file: wuaueng.dll (4/14/08) is replaced by a wuaueng.dll file which is dated: (7/30/07).
Once the computer does this anytime the updater program auto-starts or is initiated by the windows update site, the wuaueng.dll file running inside of the svchost.exe will use 100% of the primary system processor bringing the entire system to a crawl.
Ive found no fix to this issue besides stopping the windows update service and copying the newer file back to the c:\windows\system32 directory. Only bad thing is that you cant use the windows update site again as it will try to replace this file again.
If someone has a fix to this please let me know as Ive had 3 customer computers already have this issue today alone. | |

@cox.net | I am having the same issue as soon as I boot up the service host associated with windows update wuaueng.dll seizes up my computer with almost 100% use. I have SP3 installed but I too have the file dated 7/30/07. | |

Salt Lake City, UT | I have noticed the CPU usage as well and just thought my box was jacked. I now see it is not only me with this issue. I hope there is some sort of resolution to the issue. | |

| Re: [XP Pro] Wuaueng.dll / XP Sp3 Update Issues This is no Firewall issue. As noted, it started on Wednesday, May 7th, and although it does not affect every machine, it does get some. My problem started at exactly 10AM, and reappeared several times when a Windows Update decided to come to life on its own (not scheduled). I now have the problem on a second machine. I even updated to SP3 on the 2nd machine but that did not resolve to problem.
This is serious, and it is getting worse. Where is Microsoft???? | |

| Re: [XP Pro] Wuaueng.dll / Svchost.exe 100% Usage Problem. Any more info if this fixed the problem.
I Don't believe this is a firewall problem. I don't use a software firewall at all. Hardware with rules only, and I still have it. Also the service is not giving up it's CPU cycles as it should because there is very noticeable lag to the system at all times. Especially on-line when gaming. | |

1 edit | Re: [XP Pro] Wuaueng.dll / Svchost.exe 100% Usage Problem. My original concern about software firewalls (a point completely missed by BudBob  in his shouting above) was the repeated signs of a proxy failure in the update log. 90% of the time it is a software firewall client responsible for this class of Windows Update log errors. They were not being ruled in as the cause, but being ruled out as a factor. Later investigation about versioning issues with wuaueng.dll showed a looping cycle by Windows Update on certain files in the SP3 redistributable, so the discussion long ago moved away from any firewall focus.
The suggestion earlier by Apophis was an excellent one, and at the moment the accepted workaround:
Start, Run, CMD
In the black CMD session box, type (carefully):
net stop wuauserv
rmdir c:\windows\softwaredistribution /s
net start wuauserv

| After observing the boot process with Process Explorer, wuaueng.dll loads early in boot priority bringing the boot up process to a crawl and is NOT relinqishing CPU cycles so that other drivers and software can load. Using about 95% of resources it takes an unusual amount of time to get the computer any where usable with only 5% available to load the rest of the system. There is no way a simple web app should consume that amount of resources EVER. | |

@unl.pt | you are saying this is a sp3 issue, never the less it happens to me with SP2, so it's like Apophis said it's not related to sp3 but with some other issue. | |

| It has nothing to do with wether or not you use Windows Update or Microsoft Update servers.
I'm behind a WSUS (3.0) server, and get the same wuaueng.dll issue.
It's happening across 4 PC's here now in the office, all 4 PC's only talk to the WSUS server. | |

1 edit | Re: [XP Pro] Wuaueng.dll / Svchost.exe 100% Usage Problem. Most of these SVCHOST/wuaueng.dll problems involved both Microsoft and CA Antivirus software. Other A/V vendors may be involved, but the most prominent was CA. A temporary circumvention was to exclude .msp and .msi files from the real-time scanner - not a great solution, but it worked for many people. CA indicated the issue surfaced with engine V31.4, and a little over a week ago they released engine V31.5. The new engine seemed to resolve most of these issues. [Remove the exclusions!]
In a few isolated cases [no CA installed, or the new CA engine in place] the problem persisted. In these cases, stopping the Automatic Update service, then deleting the C:\Windows\SoftwareDistribution folder, followed by a reboot, did the trick. There may be other unique situations, but the corrections noted above resolved the predominant cases.

1 edit | Re: [XP Pro] Wuaueng.dll / Svchost.exe 100% Usage Problem. Your detailed fix is longer than mine, but does the same thing at its core. The DLL registration is completely off-task and unrelated material for the issue being discussed in this thread.
Longer is not better, just longer. | |

| I have been all over this particular issue and after more than a year and false hopes I disabled Automatic Updates service in the services applet.
I periodically update my Ghost image with new patches but then I also use Disk Protection in SteadyState so if I have any bad stuff get in due to a missing patch I get a new system when I reboot.
