You are not going to find it on Microsoft's website. By the way, everything I am stating falls under subjective accounting judgments.
Microsoft must disclose any relationship that is material significant. i.e., if the US Government bought 10% of their stuff they would have to disclose that. Of course, Microsoft sells nothing to the "US Government" – they sell to the executive branch, Social Security Administration, etc.
Microsoft must break out results along geographic lines. i.e. North America. Still not going to help us.
Microsoft has the option to break out results along product lines. Commercial, consumer, phone, etc.
But Microsoft does not have that type of relationship with the government to break out the results. (not saying it should not be done.)
