One OS to rule them all

Recently one of my friends, a computer wizard, paid me a visit. As we were talking I mentioned that I had recently installed Windows on my PC, I told him how happy I was with this operating system and showed him the Windows CD. Too my astonishment and distress he threw it into my micro-wave oven and turned it on. I was upset because the CD had become precious to me, but he said: 'Do not worry, it is unharmed.'

At first I could not see anything, but on the inner edge of the central hole I saw an inscription, in lines finer than anything I have ever seen before. The inscription shone piercingly bright, and yet remote, as if out of a great depth:

'I cannot read the fiery letters,' I said.
'No,' he said, 'but I can. The letters are Hex, of an ancient mode, but the language is that of Microsoft, which I shall not utter here. But in common English this is what it says:'

One OS to rule them all, One OS to find them,
One OS to bring them all and in the darkness bind them.
