Im no Minecraft expert but im sure you could easily fix the problem by deleteing Minecraft completely off your computer, and reinstalling Java. Then redownload Minecraft, and you should be good. If you still have the problem and it pisses you off that much, back up everything and reinstall Windows. If that doesn't work, seek technical support.
