This question covers Windows only. I know Microsoft makes a wide variety of other software products (Office, Exchange, etc.), I'm not interested in them, only in the Desktop Operating Systems.
First - unlike the most of you, I've read Microsoft's financial reports, and understand accounting. I know how much money Microsoft has on hand, and how unlikely this scenario is. I'm asking the question to find out what people currently think are their best options, if Windows is no longer available.
Second - this is not a troll. I know there are a lot of Windows fans here. I'm not trying to insult you. I'm asking what you would do in a theoretical situation.
Third - I'm going to be posting the same question in several places. The plan is to write an article based on the feedback I get. I am assuming that a response to this post means that I can quote you in full.
So what would you do if you could no longer buy new copies of Windows?
