    These don't come from Windows Update? I just checked mine and didn't get it offered. Still on "4.18.2104.14-0"

    Is it possible to uninstall old versions of Defender Platform in %ProgramData%\Microsoft\Windows Defender\Platform folder? Or is it better to leave it this way:

    Code:
    Folder of C:\ProgramData\Microsoft\Windows Defender\Platform
    
    02/06/2021  22:53    <DIR>          .
    02/06/2021  22:53    <DIR>          ..
    02/06/2021  19:05    <DIR>          4.18.2105.2-0
    02/06/2021  22:53    <DIR>          4.18.2105.3-0

    So is this one going to come from Windows Update? I just did a check (as of 5 minutes ago) and didn't get it offered, I'm still have "4.18.2105.4-0"

    How does one know which ones will come from Windows Update, and what ones won't?

    Afaik, all files included come from WU/MSFT, mainly from the dev channel, which gets them first.

    when I use the official ISO released from Microsoft in es-ES or es-MX language, in Windows Update they offer two Defender Platform Update, the current one and an old one the 2001 version (January 2020?) this bug is in place since the launch of v.2004 at least

    This time they're available on MS Catalog website. But sometimes MS will not post new version on the Catalog website, and you just get them through WU if you're enrolled in the Dev Channel.
