MS-DOS wasn't much more than a program loader, it wasn't supposed to protect anything. After your program did its worst, the OS was write protected, and the only thing you could mess up would be any floppy disks that weren't write protected. It was trivial to reset to a known good state.

It was easy to quantify your risk, as it only had write capabilities to the floppy disks without write-protect tabs.

That is what made it possible to just try anything, and not worry about it.

This is obviously only true of MS-DOS on purely floppy-based systems.

Years ago, it really saddened me to realize that a Dual Floppy IBM PC running MS-DOS was actually the high water mark of secure general purpose computing for the masses.
