Microsoft Windows version 1.0 - it all started here?
... well, it started in Xerox Parc, obviously, and in Bill Gates' desire to have a graphical front end for his DOS cash-cow to match what others were promising or actually delivering. Announced in 1983, it actually shipped in 1986, demanding more resources than promised. (Nothing changes, does it?)
To be honest, it's pretty rubbish. Windows can only tile, not overlap. Half the programs you'd actually want to run can only be run 'full screen' because they do things essential to running quickly. Actually, as it's not particularly pretty, let's just call it rubbish. But Bill had deep pockets, an incredible desire to dominate, and the one Ring to control.. erm, and he had DOS to beat manufacturers over the head with to make sure they bundled Windows on everything. Eventually, a version that sort of worked, Windows 3.0, was released. It still crashed a lot, so Windows 3.1 boasted that there would be no more 'unrecoverable application error's. It was true: they'd been renamed to 'general protection fault's instead. Anyway, much of what you hate about Windows now was there from the start.
Incredibly, version 1.0 was supported by Microsoft until 2001. I've no idea if the 5.25" disks here still read, and you're probably only meant to run them on a Tulip PC but you can amuse your friends and colleagues by showing them this on your desk anyway: it makes a better paperweight than it ever did as an operating system.
