Answer 1

Are you performing the proper WSUS maintenance including but not limited to running the Server Cleanup Wizard (SCW), declining superseded updates, running the SQL Indexing script, etc.?

Have you tried the client side script?

Are the updates being stuck at the client or the WSUS server?

Have the files downloaded successfully to the WSUS server? Expose the "File Status" column in the update view to check.

Answer 2

Hello there,

Try to Turn off Firewall Temporarily and see if that helps as most of the WSUS windows update issue is caused by improper settings in your AV.

WSUS is just a repository - the update process itself (on the local machine side) is exactly the same as if it's checking in with MS over the Internet. So if there was ever anything clogged up in there it could cause problems.

-Expand UPDATES > ALL UPDATES,
-right click on the header bar and select file status,
-click on FILE STATUS to sort the patches
-Scroll to the very top and then the very bottom to see which updates have a red X on them
-Right click on each problem update and select DECLINE after this try to push the updates.

I hope this information helps. If you have any questions please let me know and I will be glad to help you out.
