Even Microsoft Says that Users Should Uninstall the Most Recent Windows 11 Update

Microsoft is encouraging Windows 11 customers to delete a recent upgrade due to a technical error that can only be defined as an "oops." According to reports, the optional update is causing many applications to crash. The issue includes a relationship between the update and the. Net Framework included with Windows. It is currently unknown which applications are impacted by the problem; thus, uninstalling them is the only realistic remedy. 

KB5012643, the update in question, was published on April 25. It is an incremental operating system upgrade with several minor modifications. The update's release notes include a section titled "Known issues with this update." This section says that it may cause some .Net Framework 3.5 programs to cease operating. Microsoft states, "Affected apps are using certain optional components in .NET Framework 3.5, such as Windows Communication Foundation (WCF) and Windows Workflow (WWF) components." The .NET Framework is pervasive in Windows and is used by several application developers as a code foundation. Some applications will now crash or refuse to launch with this update installed. This update is exclusive to Windows 11 21H2 users, according to Windows Latest.


Microsoft has not yet released an official remedy. However, removing the update cures the problem for impacted users. Microsoft has published thorough instructions on rolling back to a prior version of the operating system for individuals having issues but not explicitly advising customers to remove the update. We can read between the lines. 

However, this update contains important security updates that will help keep your system secure. So, if you are not experiencing any issues after downloading it, there is no need to uninstall it beforehand.

How to Uninstall The Windows 11 KB5012643 Update

Open the Start menu, then enter "Windows Update Settings" to delete the update. Click "Windows Update" then 'View Update History' from there. 

Next, click on "Uninstall Update" and then select KB5012643. Click on "Uninstall." 

Hopefully, this will resolve the issue. However, you may discover that additional problems that the KB5012643 upgrade did resolve have now resurfaced.


Attempt to Enable the.NET Framework 3.5 in the Control Panel if that fails. IT administrators and skilled users may also activate it using an elevated command prompt. Here are the commands:

dism /online /enable-feature /featurename:netfx3 /all

dism /online /enable-feature /featurename:WCF-HTTP-Activation

dism /online /enable-feature /featurename:WCF-NonHTTP-Activation

This upgrade also broke Safe Mode, in addition to the mess above. According to Microsoft, users who launched into Safe Mode without networking may see a screen flicker. The company also said that explorer.exe-dependent components such as File Explorer, the Start menu, and the taskbar might look unstable. Microsoft has previously released a Known Issue Rollback (KiR) for this; thus, it should be resolved immediately. If this happens, you should be able to fix it by turning on network support in Safe Mode. 

This is only another chapter in the Windows 11 upgrade process, which has been an emotional roller coaster. The company has made several helpful adjustments, such as allowing one-click browser default settings. However, when a "Windows is updating" warning appears, most customers begin to sweat. It is reminiscent of Windows 10 upgrades released as recently as the previous year. Back then, Windows 10 and printer drivers were notorious for causing BSODs. An upgrade in April of last year also destroyed gaming performance. Caution should be used while downloading optional updates, including cumulative and driver updates. However, security updates should continue to be implemented.
