QNX

This is a quick demonstration of the QNX 1.4 megabyte floppy disk demo.

QNX is an advanced, compact, real-time operating system. This demo disk, released in 1999, fits the operating system, the "Photon MicroGUI", and the HTML 3 capable Voyager Web browser all on a single 1.4 meg disk!

So far no emulator or virtualizer I have tried will run this QNX demo 100%, so this is running on real hardware. The video is captured with a VGA capture device.

QNX is one of the most intriguing operating systems of all time. This demo disk is one of those things that, even today, blows my mind. Be sure to watch through the whole video, especially the part where extensions are downloaded and run from the web, all on a single 1.44 MB floppy.

Putting WinSXS on your 2TB drive would defeat the purpose of having Windows on the SSD, since it gets accessed a lot for compatibility reasons, such as when a program needs an older version of a DLL. It also can't be on another drive, since it's made up of hardlinks, which can't link to files on other file systems. At the same time, that means that it doesn't actually take up 11.5GB of space - Explorer doesn't handle hardlinks intelligently when calculating file size and disk usage. Interestingly, Explorer does calculate disk usage for sparse files correctly.

Still, it is possible to shrink it (and quite easy), but you'd lose the ability to uninstall updates or service packs.

As for the other things, well, sure it'd be nice, but it really isn't that big of a deal. For the majority of use cases, the convenience and predictability of having those parts stored locally outweighs the benefits of saving 8 or 9 gigs.
