  1. I originally had windows 7 home premium but ''naughtily'' (nothing to do with water) upgraded to windows 7 ultimate. If I re-install/repair windows using the original product key should I use the product's original windows (7 home premium), or the windows it was running before the re-install/repair (7 ultimate)?

  2. I just did this and it did not work. It went through the installation process as normal but towards the end it says there was an error and a red box popped up. My retarded ass didnt bother to write the numbers down to look up, I just clicked ok and then it began to reinstall previous version of windows and I am back where I started. Everything else worked and went as planned.
