A recent news story said that there have now been about 175 million licenses sold for the Windows 7 operating system, making it the fastest selling one yet. That's probably because there were about ten million of us helping to test it during its beta phase, and we all had a chance to submit feedback and ideas for it, and by the time it was released, it was as solid as a rock, and a huge improvement on the previous Vista system. I've been using Windows 7 now ever since that first beta came out in January of 2009, and it's great. If you haven't tried it, you should.
