There are some strange builtin entries from Windows. Like why do I have the option to "play" a jpeg on any Bluetooth headsets that are paired with my laptop? I just found out that besides "open with" and "send to" there is a third way to open a file using "share" to share a file with an app.
The most useless entry is probably from AMD Radeon software. Two entries on the very top of the context menu on every folder. I would understand if it appeared in the menu of the Desktop folder, but not on every single folder no matter how deep in the file structure.
Just clean out the entries you don't need. Blame microsoft if that means having to dig into the registry.
This is the whole point to why Microsoft took this awkward step.
You can make the case for a new API to avoid orphaning, and for greater traceability - and also, hopefully, for better performance. But I sure hope the end result will be more usable not less, and I'm pretty disappointed that this intermediate step is such a step backwards.
