How do I uninstall WSUS windows update agent? RRS feed

  • Question

  • My server at some point was managed by WSUS. I removed WSUS and deleted group policy relevant to WSUS. It still seems to be having some effect and my server is trying to pull updates from some strange location "win7_prerelease" instead of proper URL. It also tries to pull something off test.update.microsoft.com instead. I have tried all the fixes I found but WU agent keep pulling stuff from those strange locations.

    I'm on Windows 2008 R2 SP1

  • Turns out issue was that Windows Intune uninstallation was not complete and it left crippled Windows Update agent on a system. Follow this link and there are steps outlined how to fix the issue (uninstall old agent and install new one). http://mymfe.microsoft.com/WindowsIntune/Feedback.aspx?formID=615

  • Assuming you don't have a weird group policy configured setting that, one thing you could check would be whether there's anything in the servers registry settings configuring that. In regedit check out :

    HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate

    and see if those paths appear under WUServer key. If they do then I think the easiest option is to simply delete the entire WindowsUpdate key (obviously back it up before you do it), since I believe Windows update will function without it, but without any of the custom settings that you could configure via the registry to talk to your WSUS server.

  • That key does not exists. My computer is in Workgroup and not part of domain. I'm not sure where Windows Update agent pulls this weird URL for updates containing "prerelease" words and specifying "test.update.microsoft.com"

  • Hi,

    I noticed that the server is trying to connect to a proxy server but failed. And there are several way to configure a proxy server. I recommend you follow the article find out where it is configured.

    How the Windows Update client determines which proxy server to use to connect to the Windows Update Web site

    Hope this helps.

  • I don't use proxy and it's not configured either. It would not matter actually is proxy would be used or not since URLs which Windows update is checking are wrong, all those are end up in HTTP 404 error message if accessed directly.
