The software giant admitted in a support document that Windows 11 update causes.NET 3.5 framework components to become unstable. The.NET Framework is a free, open-source platform used to build and run programs on Windows, and is relied upon by many apps.
Some.NET Framework 3.5 apps might not open after installing this update. Affected apps use optional components in.NET Framework 3.5, such as Windows Communication Foundation and Windows Workflow.
This particular update is optional, so while it promised a few dozen fixes, it probably hasn't been installed on your system. The bug doesn't affect every app, only those using certain.NET 3.5 elements. If you are having issues with certain apps on your PC, and it is running an update, you should uninstall it.
To open the Start menu, type "Windows Update settings" and choose the highlighted option. If you use this search, you can find the culprit by pressing on it, and then choosing "uninstalling" on the page.
You will need to reset your system for the change to happen. The latest bugs should be removed from your computer once it does. Microsoft suggests re-enabling.NET Framework 3.5 and the Windows Communication Foundation if you don't want to uninstall the update. The following commands need to be run in the terminal.
dism /online /enable-feature /featurename:netfx3 /all
dism /online /enable-feature /featurename:WCF-HTTP-Activation
dism /online /enable-feature /featurename:WCF-NonHTTP-Activation
This particular error is not significant to most Windows 11 users. It follows a string of recent bugs, including one that broke safe mode. Since the launch of Windows 11 six months ago, there have been few major issues. It comes on the heels of a disastrous timeline when it felt as if every Windows 10 update did more harm than good. We hope Microsoft cleans up its act before something serious happens.
