For my user account, the Windows Push Notification Platform seems to be messed up. I have the following symptoms:
In the

.Visual Studio fails to install an app that is capable of toasts and live tiles with the following error:
Error 1 Error : DEP0700 : Registration of the app failed. error 0x80072EE4: The Visual Elements extension failed while processing the Notification element. (0x80073cf6) MenSaar

. While writing the registry entry, explorer.exe
has the following stack:
