Microsoft has an image problem with November's Windows security update

The issue affects images rendered with a height or width of zero at the selected printing resolution. These might not be visible to users, but can form part of a document's watermarking or layout.

After the update, those invisible objects can apparently make the printed document disappear too. Microsoft said: "The issue was observed when printing Microsoft Word documents using the Windows Graphics Device Interface (GDI), but printing from other applications might also be affected."

According to the notification (WI1549472), most versions of Windows are affected, from the latest Windows 11 26H2 through Windows 10 Enterprise LTSC 2016. Windows Server from 2025 to 2016 is also affected.

Users need not have added these objects themselves. Microsoft says document-generation tools can insert them even when no graphic is visible.

Printer problems aren't the only issue requiring attention. After installation of the November 2026 security update, Microsoft warned that "certain Windows activation and licensing operations performed using the Software Licensing Management Tool (SLMGR) might fail."
