A Microsoft file hosting and synchronization service.
Interesting observation, thank you; and I hope it gives Microsoft some direction to research. It's clearly not the only cause, as I have no such modifications, and I assume that most users also do not make such modifications to the default right-click menu/ most users do not use optimization applications.
Interestingly, I have not seen the issue arise in some time (at least a couple of months? more?).
similar issue, when i press WIN+E, it does not launch explorer but this popup error message.
the cause is that i disabled some right-click menu items in an optimization app. When restored these changes, problem solved.
the related items are:
- open in new process
- open in new tab
- open in new window
