Microsoft issued a service alert warning that its November 2026 security updates can cause printing failures on Windows Server 2016+ and Windows 10+ devices. The bug affects documents containing images with zero height or width—often invisible watermarks or layout anchors—and mainly hits Word documents printed via the Windows GDI interface, though other apps may also be affected.
Microsoft confirmed that Windows Server 2016, originally released in October 2016, will receive its final security update in January 2027, after which no further patches will be issued. The cutoff applies to all editions, including Datacenter, Essentials, MultiPoint Premium and Standard, and will also end support for Essentials-specific features like Remote Web Access.
Microsoft has acknowledged that the August 2026 security update can cause 0xc0000409 errors tied to CompatTelRunner.exe on Windows Server 2016 machines running the Compatibility Appraiser telemetry service. The bug affects both physical hardware and virtual machines, including VMware and Azure deployments, generating repeated Application Error log entries under Event ID 1000.
