There is a menu item named "Open in DeoVR" which shows up when right-clicking on video files in Windows 10. This is not removed by the uninstall process, and it remains after multiple reboots. I've looked for the item with tools like ShellMenuView but it doesn't appear to be there. I presume there are a bunch of registry keys that DeoVR added but didn't remove, but the registry is very large and I need some help if I'm going in there.
How can I remove this remnant?
