For November, Patch Tuesday includes three Windows zero-day fixes
Briefly

The Readiness team provides important guidance following Patch Tuesday, ensuring critical updates for networking, security, and filesystem are rigorously tested for maximum application compatibility against affected Windows platforms.
Testing requires covering diverse areas such as VPN, Wi-Fi, and Bluetooth to guarantee functionality post-update, particularly for certificate authorities and Windows Defender Application Control.
Specific updates like the changes to the NTFileCopyChunk API necessitate internal application testing, particularly in regard to ensuring parameter validity and directory notifications.
For users still reliant on dial-up connections, the November update to the TAPI API mandates testing to affirm continuous connectivity after system updates.
