Microsoft rolls out emergency update for Windows 11's latest patch — recent update causes crashes on AMD graphics, Explorer hang-ups, and broken third-party integrations

Microsoft hastily released an emergency update for its Windows 11 operating system following recent reports of a myriad of bugs and malfunctions caused by their September 2026 patch. The update, which addressed nearly 1000 security vulnerabilities, introduced several new features and improvements, including a movable taskbar reminiscent of Windows 95, customizable Start menu layouts, and enhanced Windows Search functionality.

However, the update has also triggered a range of problems for Windows 11 users. AMD Radeon graphics card users have been encountering system crashes, potentially due to driver instability provoked by the patch. Reinstalling the driver has proven ineffective for many users, as the issue affects most contemporary AMD graphics cards.

Remote Desktop Services (RDS) users have reported instability, causing connection and sign-in failures. Audio devices have also been reported to go dead, with some experiencing a botched configuration upon startup. The File History backup feature has reportedly stopped detecting external drives, rendering it ineffective. Enterprises, system administrators, and homelab users have been particularly impacted by these issues.

The emergency patch aimed to address the Remote Desktop Service issues and a problem with Claude Cowork, which became nonfunctional due to the update breaking HC-managed Linux VMs with Plan9 shared folders. However, HP and Lenovo system owners are advised to postpone the update, as they've encountered BIOS corruption and power mismanagement problems. Despite Microsoft's improved development speed and responsiveness to customer feedback, a series of bugs following major feature updates remains a common occurrence.
