so why wouldn't this work?
12 May 2014
Dear Microsoft
12 years ago I bought an os from you, which has been plagued by a never ending series of security problems. I've given you plenty of time to fix the problems, but 12 years on I read in the press that there some more problems have shown up, and you have given up trying to fix them. As one of the fundamental aspects of an is us to stop random computers on the internet from stealing my data, I have no choice but to view your os as not fit for purpose, and I would like a full refund.
Yours faithfully
Mark
