Microsoft: September updates cause RDS failures on Windows Server
Microsoft has confirmed reports that the September 2026 security updates cause Remote Desktop Services (RDS) failures on Windows Server systems.

Microsoft has officially confirmed that the recent September security updates are causing issues with Remote Desktop Services (RDS) across various Windows Server systems. The glitch has disrupted remote management capabilities and sparked concern among network administrators.
Reports indicate that after installing the updates, users experience connection failures and instability within the RDS environment. Microsoft engineering teams are currently investigating the root cause and working on a reliable fix to resolve the issue for affected environments.
Such unexpected bugs in core server components can significantly disrupt business operations, emphasizing the critical need for rigorous testing environments before deploying patches globally. IT teams worldwide are closely monitoring the situation for workaround solutions.
For tech professionals and system administrators, this serves as a reminder to exercise caution with upcoming patch cycles. Pausing non-critical server updates until Microsoft releases a verified hotfix is considered a prudent approach.
