Wait, DOS stands for Dirty Operating System?

ha, i felt that too. ive been wrong for how many decades??

I believe Microsoft tactfully and retroactively changed it to "disk" once it went commercial with IBM.

It also helped that at the time there were several "disk operating systems" for various platforms, which is why the MS- part on MS-DOS was important.

That really explains a lot, and why MS jumped to Windows NT, they knew that DOS would always be Dirty.
