Do you have a machine that, in the past, was configured to use WSUS, but has now been moved and is unable to receive updates because the WSUS settings are bad? I ran into this and decided to document the steps.
The easiest way to clear out the WSUS configuration information is to wipe out this registry key.
After clearing it out, restart the “Windows Update” service.
This also may reset some Windows Update settings, for instance, the one that decides if updates should install automatically or after asking permission. You’ll want to check that out.
You may find yourself getting a “0x80244010” error when trying to check for updates. This error seems to be related to the Windows Update client making too many requests to the server. It should work itself out if you try checking for updates again, perhaps two or three times. If it doesn’t, another solution is to backup or delete the
folder. Then, restart the “Windows Update” service again and try checking for updates once more.
Note, if your machine is attached to a domain and that domain is providing WSUS configuration information, the WSUS settings will be restored to those configured by the domain whenever you log in. You’ll want to check with your domain administrator if there is a problem with how WSUS is set up.
