Microsoft took a while to figure out that the A: assignment is pointless as the era of Floppy drives is now over. This has been fixed in Windows 11 Build 22000 (stable). Starting with Windows 11, Device Manager no longer defaults to A: i.e it doesn’t ask you for a floppy disk for drivers (icon has also been replaced).
Device Manager can now automatically detect the OS drive, so you can easily locate the driver package if you extracted the downloaded zip file to a folder on the system drive.
Everything about this user experience is terrible, but at least the ditching of A: makes it slightly less terrible. I can’t believe we’re at Windows 11 in 2022, and this UI is still identical to what was first shipped in Windows 95.
