Smooth Upgrade to Windows 10

Microsoft updated my desktop to Windows 10 from 8.1 today. So far so good. The update was very smooth, took less than 30 minutes, and all my settings were preserved. The new Edge browser seems seamless. Still navigating the new features, like Cortana, and will observe the following days, but if initial indications hold, then this is one great update for sure. Thanks, Microsoft!
