It wouldn't ever come to this, but even theoretically, you haven't thought through what would really transpire.
1) The Feds do have guns, but Microsoft has an extraordinary amount of goodwill, and media connections, and political connections, the foremost being the POTUS. He would not dare piss off one of the most powerful corporations in the world and risk the ensuing media malestrom that would have heads rolling from his office on down. They say our goverment has 3 branches, but it really has 4, the 4th being the intensely powerful news and internet media, which microsoft's tentacles even today spread very deep, and from which all politicians draw their votes. If it came to this, the president would face increasing scrutiny and actions of congress to block whatever he wanted to do (especially a republican congress) in order to save their own ass.
2) All these other agencies are enforcement angencies and fall under the jurisdiction of the POTUS. They would not act quickly (and would have to follow legal procedure, it's not as if these orgs just jump when the president says "sick em boy").
