Loading Synchronization history from the past one month and still it;s 70%

In Windows Server 2019, we're running WSUS 10.0.17763.1. We had to remove and re-add the role due to a WSUS problem. After that, it's Loading Synchronization History for the previous month, which is still at 70%. I'm not sure how I'm going to do it quickly.

    This will keep happening if you don't perform all of the proper WSUS maintenance. Quick fix for you

    truncate table tbEventInstance

    This will remove all sync history so you can load it.

    Again, if you re-installed properly (deleting the database and any trace of WSUS as depicted in my guide), you wouldn't have this issue because there would not be any sync history to load other than a few syncs.

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performing the proper WSUS maintenance including but not limited to running the Server Cleanup Wizard (SCW), declining superseded updates, running the SQL Indexing script, etc.?


    To quote myself:

    Just because you’ve installed a new WSUS server, doesn’t mean that it’s clean or optimized; it just means that it’s NEW!

    Also, if you just reinstalled WSUS, and you're experiencing prior sync history, then it sounds like you didn't reinstall it correctly.

    Thanks for your response.

    Please try to run the wsusutil.exe command first and then confirm whether the issue will be resolved or not.
    Open cmd as an administrator and navigate to wsusutil.exe tool. Then run the wsusutil.exe postinstall command:
