Mount USB flash drive or external hard drive on Windows as drive letter A: or B:?

Is there any way to get Windows to assign drive letter A: or B: (instead of D: or a subsequent letter) to a connected USB flash drive or external hard drive?

(This is purely for nostalgia purposes, because I miss the days when A: and B: were assigned to floppy drives!)

It won't do that automatically when you just plug in a USB drive. (It will pick the first available letter after the regular hard drives in that case.)
But you can manually assign A or B via the Disk Management in Control-Panel or via diskpart and Windows will remember that the next time you insert that same USB drive.

(PS: You can also assign A: or B: to a network-drive. Something most people don't know either.)
