Windows February 2021 Patch

[Michael]

Hi all,

 

This patch is massive and I've already started to deploy to Windows Server 2016 servers. A description of what it plugs is here including a zero day vulnerability.

 

One thing that caught my eye -

 

This security update includes quality improvements. Key changes include:

 

Enables administrators to disable standalone Internet Explorer using a Group Policy while continuing to use Microsoft Edge's IE Mode.

 

Updates Internet Explorer’s About dialog to use the standard modern dialog.

 

This also enforces the RPC lock on DCs, first reported in August 2020 (Zerologon).
