Windows 10 V1803: Issues with Update KB4462933

[German]Microsoft released cumulative update KB4462933 for Windows 10 V1803 in October 2018. This update caused the Edge Developer Tools to stop working. There may also be problems with SQL connections.


We are talking about cumulative update KB4462933 of October 24, 2018, which raised Windows 10 V1803 (April 2018 update) to build 17134.376. I mentioned the update within the blog post Windows 10 V1803: Update KB4462933 (10/24/2018).

Issues with Edge Developers Tools

The update should actually fix, among others, a number of bugs in Edge Developers Tools. Microsoft wrote:

  • Addresses an issue that sometimes prevents documents from appearing in the Microsoft Edge DevTools debugger.
  • Addresses an issue that sometimes prevents Microsoft Edge extension scripts from appearing in Microsoft Edge DevTools.

WindowsLatest it has now become apparent that Microsoft has added a Known Issue to the KB article KB4462933:

Developer Tools (F12) may fail to start in Microsoft Edge.

If someone really uses the Edge DevTool, Microsoft suggests deleting the following registry entries with administrative permissions as a workaround..

Using Administrator permissions, delete the following files and restart Developer Tools:

On an x64 machine: C:\Windows\SystemApps\Microsoft.

On an x86 machine: C:\Windows\SystemApps\Microsoft.

Microsoft is working on a resolution and will provide an update in an upcoming release.

Microsoft describes a second SQL Connection error that may occur in conjunction with a .NET framework update. Microsoft describes the error as follows:

After you install the August Preview of Quality Rollup or September 11, 2018 .NET Framework update, instantiation of SqlConnection can throw an exception. For more information about this issue, see the following article in the Microsoft Knowledge Base:

Microsoft is working on a resolution and will provide an update in an upcoming release.

    Este KB4462933, depois de instalado, passou a exigir ativação do Windows 10. Internamente no PC, vi de que foi encontrada uma chave para Windows 10 Home instalada e não do PRO. Nunca usei o Home, pois deste o início sempre instalei o PRO, e cheguei a ser Insider. Como essa chave repentinamente foi parar dentro do PC. Dizem que se um hardware for trocado como, Placa mãe ou processador perde-se a validade do Windows grátis. Nunca troquei nada a não ser uma WebCam Logitech C270 que pifou, por uma antiga Philips. A Microsoft tem todo o histórico de cada PC, mas vai entender qual a artimanha dessa exigência de ativação. Acabou a validade de se usar gratuitamente o Windows 10, após este KB?
