27-year history of Windows in pictures & details:

I tried that 80s Windows on a floppy thing a few years ago, and don't know how people coped with such stuff, but then again they didn't know about future versions usability.
I don't know either.
Floppies have to be the world's worst for losing their formatting, or having an error, or even becoming unusable & un-writable.
Floppies are more reliable when files are erased instead of formatting, because formatting can kill a perfectly good floppy dead.
They are flaky & may work great, but then not work the next time you use them. Slow, unreliable, & I don't know how people coped either!
I enjoyed my sense of power over the machine when by Bat file reached
GOTO :LOOP
and the floppy had to clatter through to the end of file and start reading again from the beginning
