I recently noticed a new icon in the system tray of my PC (I'm currently running Win7 Pro). For reasons unknown, Microsoft has apparently decided to offer me a free upgrade to Win10, full version, no strings attached, to be made available on July 29th. I'm not so sure what their angle is, but a free upgrade sure sounds tempting. Since there are a lot of people posting here with a lot more PC/IT/Web savvy than myself, I'd like to hear their opinions regarding the wisdom of this upgrade. I'm pretty content with Win7, but if I can get something newer for free from the normally-rapacious Microsoft, it sounds like a good deal. It also sounds a bit like one of those "too good to be true" offers. Informed opinions/insights welcome.
