It’s tempting to roll back the update and print your file. Resist that, because the November release closes about 1,094 security holes across Microsoft products by one count, and removing it puts them back on your PC.
Microsoft’s own release-health pages tell people to install the latest security update because it carries important fixes. When an August 2026 .NET Framework update broke printing in some apps, the same logic applied: uninstalling it would have reopened the flaws it patched.
That August episode also shows how Microsoft tends to handle these trade-offs. Its temporary workaround for developers switched off new protections added by that update, and Microsoft admitted this could widen the attack surface. It recommended the switch only as a short-term measure when there was no other choice.
For the November printing bug, Microsoft hasn’t published any workaround for home users yet. If a document is urgent, the safer path is to keep the update and wait for an official fix rather than strip security patches from your PC.
Windows printing has broken like this before
This isn’t the first time a Windows update has tripped over printing. In March 2025, an update caused USB printers to spit out random text. In July 2025, another one broke the Print to PDF feature.
Then came August 2026. That month, apps built on Windows Presentation Foundation, a toolkit for app interfaces, could fail when printing or saving PDFs after a round of .NET Framework updates. Those apps threw a System.IO.FileFormatException error with content using certain character sets, and Microsoft pointed to the standard Calibri font as one example. Visual Studio and SQL Server Management Studio were among the apps at risk.
November is busy on the bug front as well. The same security update has caused Windows activation failures with error 0x80041008 for some business PCs, and updates released since the October Patch Tuesday have caused SQL Server performance and stability problems.
