On Windows 11, I have added a custom context menu item for .stl files by adding a new key in Computer\HKEY_CLASSES_ROOT\SystemFileAssociations\.stl in the registry that links to the .exe I want to use: "C:\Program Files\OrcaSlicer\orca-slicer.exe" "%1".
The command itself works fine, but I would like to add the icon of the program in the context menu. However, this does not seem to work. Multiple guide I found online say that you should add a 'Icon' String with a link to the icon, but this never works. I have tried linking to the .exe of the program itself, I have tried extracting the .ico files and linking to the 32x32 and 256x256 .ico files, I have tried linking to an .ico on a different drive, nothing works.
Icon REG_SZ "C:\Program Files\OrcaSlicer\orca-slicer.exe"
What could I be doing wrong?
