Microsoft has recommended that Windows 11 users uninstall update KB5012643 from their machine, due to a recurring issue launching system apps.
If this sounds familiar to you, that’s because it was initially reported over a week ago, alas the situation seems to have gotten worse since then. This means that the problem is now more widespread and causing havoc for users who will attempt to launch (many) applications built on the .NET 3.5 framework. The anomaly causes a crash or even a total launch failure.
As Windows Latest reports, users have reported that ShareX, KeePass, Discord, and the Visual Studio installer are just a few of the apps used. A user on Feedback Hub claimed that even Microsoft Teams refused to launch after installing the update, as per the following error message: “The process ended with code 3221225781 (0xc0000135)”.
Does anyone encounter error after KB5013628 / KB5013943 – Application failed to start correctly (0xc0000135) unable to start .NET 4.8 programs – bing/visual studio etc. # Windows11May 11, 2022
Microsoft doesn’t have an official solution, but it appears uninstalling the update resolves the concerns – and while the company hasn’t told users directly to do so, it has provided step-by-step instructions on the way to go back to a previous version of the operating system… for any user encountering this type of difficulty.
Either way, the offending version contains important security updates to help better protect your system, so if you are currently not having any issues after installation, there is no need to remove it from your system. preventive way.
To uninstall the update, open the Start menu, then type “Windows update settings”. From there, click on “Windows Update” and then on “View update history”.
Next, select KB5012643 and then click “Uninstall”. This should resolve the issue. But beware: other bugs, eliminated by the KB5012643 update, may be back soon.
Hopefully, Microsoft will release a new KB5012643 update that fixes these issues without introducing new ones.
The situation becomes embarrassing for Microsoft
The constant release of software updates, adding problems instead of eliminating them, proves quite humiliating for Microsoft, given its significant history of faulty Windows 10 updates. And recommending uninstalling the latest Windows 11 update may cause users to lose faith in Microsoft and its OS.
With Apple offering relatively affordable laptop and desktop alternatives (through the MacBook Air and M1-equipped Mac Mini), some might start to wonder if the grass isn’t greener elsewhere. .
