On my of my WSUS servers (Upstream and downstream) the DB has grown to over 15 GB. Our estate is small (~1400 windows machines). I notice that the table tbXML is ~ 6 GB. It seems to contain localization data or the like. I'm only selecting English under Options -> Update Files and Languages File -> Update Languages

Does anyone know the purpose of this or how to safely clear it down?

    @shockoMS
    Thanks for your posting on Q&A.

    I don't know what the actually datas are included into the table tbXML. There is no such Official Document for reference. But I tried to test it in my lab and I would like to sahre the test result with you.

    I ran this PowerShell Scripts to decline the Superseded updates and run the Server Cleanup Wizard. Some datas are deleted from the table. Here is the screenshots for you:
