3DBrowser icons sometime appears instead application icons in the taskbar

Windows 10 sometimes displays bad icons for application in the taskbar.
Depending on your settings, the icons might be a 3DBrowser icon.
Below is the way Acrobat Reader might appears in your taskbar.

The problem is due to a problem in the way the taskbar extract the icon from the application.
It uses the application that has been associated with the .ico extension.
The problem is that once an application has been selected for opening such kind of file, then its icons is used in the taskbar.
If you used 3DBrowser for opening .ico files, then you'll see a 3DBrowser icon.

The only solution (do it carefully and do nothing if you are not sure) is to delete the following registry key, using regedit.

Ordinateur\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ico\UserChoice

Once this has been done, you must kill the explorer.exe tasks, or restart your session or restart your computer.
Normally you'll then see the correct icon in the taskbar.

Now acrobat reader appears correctly in your taskbar.
