The latest Windows 11 update does more harm than good

Latest optional update KB5012643 for Windows 11 (21H2), which was designed to solve problems with the screen flickering in Safe Mode without network driver support, as well as the broken functionality of some services, such as B. the file explorer or the start menu, actually causes more problems than it’s worth. The company recommends removing it and reports that it is already working on a fix.

It turned out that the update also affects some applications for Windows 11 and interrupts their work. In particular, problems occur with applications that use the .NET Framework 3.5. Although Microsoft itself has not described all the potential problems caused by the update, in particular it does not allow you to run applications that use the said framework. The problem does not affect all applications using NET Framework 3.5, only those using Windows Communication Foundation (WCF) and Windows Workflow (WWF) components.

A workaround is to uninstall update KB5012463. If for some reason this is not possible, another solution is to restart the .NET Framework 3.5 and WCF in the Windows OS Components and Services list. To do this, open a command prompt and enter the following commands:

  • dism /online /enable-feature /featurename:netfx3 /all
  • dism /online /enable-feature /featurename:WCF-HTTP-Activation
  • dism /online /enable-feature /featurename:WCF-NonHTTP-Activation

Microsoft is working on a more reliable solution to the problem and will provide it with a new operating system update. The company has not specified when this will happen.
