If you use any operating system that doesn't start with a "Microsoft" and end with a "Windows" (and some kind of short letter or number designation), then you have utterly failed in your attempt to keep heathen software elements from besmirching the good name and reputation of your precious PC. And woe unto any who utter the forbidden name of a common Silicon Valley manufacturer of said "different" operating systems around these parts--you can trust me on this one. I learned the hard way.
But let it not be said that I wouldn't rise up to the challenge, see the error of my ways, and accept my restatement into PC-only territory with a bit of grace and/or slice of humble pie. I have even made a great sacrifice to prove my noble intentions:
