I've been trying several iterations of the beta and love it as much as W7 previews back in the days, but I still have some apprehension about upgrading "for good" using the upgrade tool, I've usually always done clean installs I'm not really ready to do now. Especially on my "pride" home desktop that has been running perfectly smoothly (even better than a 2014 build) on the very first W7 install from when I built it in 2010 despite no antivirus, much gaming, about 350 installed programs of which dozens of development/experimental tools. Just can't upgrade this thing, it's a living testament of how reliable W7 was (and still is) with the load of mess it's endured over the years.
