Overview
This cumulative update for Windows Server, version 23H2 (KB5073450), includes the latest security fixes and improvements, along with non-security updates from last month's optional preview release. It addresses several known issues, including problems with cloud storage, Remote Desktop connections, and Windows Deployment Services. The update also removes older modem drivers, updates a core Windows component, and introduces a security hardening behavior for credential autofill.
General Purpose
The key improvements and changes in this update include:- Removal of older modem drivers that were causing compatibility issues- Security hardening to restrict certain applications from autofilling credentials during remote support sessions- Fixes for an issue causing apps like Outlook, Teams, and Excel to crash when typing text- Changes to Windows Deployment Services to stop supporting hands-free deployment by default- Update to the WinSqlite3.dll component to address security vulnerabilities- Inclusion of the latest servicing stack update to ensure a robust and reliable update process
General Sentiment
Overall, this update appears to be focused on security improvements and bug fixes rather than major new features. The removal of older modem drivers and the security hardening around credential autofill suggest Microsoft is prioritizing system stability and security. While there are a few known issues, such as problems with cloud storage and Remote Desktop connections, the majority of the changes seem aimed at addressing compatibility and reliability problems. The update is likely to be well-received by IT administrators looking to keep their Windows Server 23H2 environments secure and running smoothly.However, the lack of major new functionality may disappoint some users hoping for more substantial improvements. As with any update, it's important to thoroughly test in a non-production environment before deploying broadly, especially given the known issues reported.
