This is a question that just popped into my mind and I can't help but wonder why it's still common for a Windows installation to be installed on C: with all other drive letters going up from D: to Z:. In the early MS-DOS times, all we had were floppy disks and they were at A:. When the 3.5 inch floppy started to replace the 5.25 floppy, many people had an A: and B: drive. Then the hard disk became popular and the hard disk was at C: because A: and B: were taken. Then the 5.25 floppy disappeared and most computers had a gap between A: and C:. Nowadays, the 3.5 floppy is just too outdated so A: disappeared too. All disks now start at C:.
Yeah, I know I can assign my own drive letters and I've done so with my data disks. My installation disk will just continue to be stuck at C: and I don't really mind. I have no problems with drive letters.
But why do the new Windows versions just continue to install themselves by default on C: instead of assigning the letter A: to the boot hard disk?
