Historically, MS published IE11 fixes as separate KB fixes for 2012 and 2012R2 on a monthly basis or whenever they had updates.
Windows server 2016 and 2019 had IE fixes incorporated into the monthly cumulative hotfix for any given month.
Now with Edge on server 2022, that has changed apparently. If you visit the MS catalog and search for “edge”, https://www.catalog.update.microsoft.com/Search.aspx?q=edge, you will see their security updates for vulnerabilities in Edge but no KB number scheme.
Anyone else figured out what they plans are for keeping Edge up-to-date on server 2022?
I opened an advisory case with MS too on this topic.
