Why do you need a separate PIN anyway? Shouldn't your Windows password be enough? Having to enter two different codes makes it unlikely a majority would use the system. I would be surprised if iOS or Android required a separate PIN for encryption.

You need a separate pin because windows lives on the encrypted disk so you need to decrypt it before you can boot completely.

		macOS solved this (and a lot of other problems) by putting the OS on a separate read-only partition - technically an APFS volume - that doesn’t get encrypted. Microsoft’s backwards-compatibility obsession might not let them make that the default, but they could at least make it an option.
