This little utility does exactly what it suppose to, nothing more. This contrasts brightly with tools like powertoys which have much bloat (useless features, UI, etc.), while not even being able to remap system keys.
mcbookdel remaps Right Option key for Windows DEL key in your Bootcamp OS. So now you can finally use proper Delete key with single key press (albeit in a bit weird position)!
As a bonus, it also remaps Right Command key as Middle Mouse Button key, which is very useful when you don't have proper mouse connected to your Mac/MacBook.
Note: to work properly in all programs it must run with elevated permissions (Admin Mode). Autostart is implemented as automatic creation of Task Scheduler entry.
