Bottom line is that unless you're here in the US (and even then it would be difficult) there is no way for them to stop you from using their software once you've bought a license.
For one it is nearly impossible for Microsoft to stop someone in another Country without the direct help of their Government laws supporting the claims of wrong doing and then there is still a high cost in legal fees that most small companies just can not afford to pursue.
Even if you were pirating their software in another Country they are probably too small to be able to do much about it, but that sure would suck and mean that you're being a [censored] about it.
How would you like it if someone came along and took money off your table?
You buy the license, use it for anything you want, just please don't be a low life and give it away to others to use for free, be an up and up person about it and treat it as you would want to also be treated.
