Microsoft is going to start validating copies of windows before allowing updates. Now all the people using illegal copies have a good reason to try linux! Other than that, they have the choice of using un-patched windows versions or paying a ridiculous amount of money for windows. I'm actually a little surprised it took MS this long to do such a thing, priracy has been a big issue for them.
