Ok - from start to finish from blowing away the partition on the SSD to full reinstall of OS Win10Pro, to using my Microsoft account (which btw caches the OS key + settings and links it to your account), reinstalling Office 2013, downloading AH (even though the game works in the directory without a reinstall), downloading a couple of my fav games, it was just 2 hours. That blew me away on how fast it is. And that includes installing and setting up Windows Mixed Reality and SteamVR.
Before, loose a hard drive and do a reinstall, we're talking a weekend project and a couple week nights before it's 100%. But my Gmail account caches my Chrome, MS caches my Win10Pro preferences and OS settings (all except my screensaver), and I don't have any local mail clients as I'm using Gmail and iCloud. I also didn't install JAVA. What games uses Java anyways? NONE. Only Adobe product I installed was Acrobat Reader - and that took 4 minutes.
God I love SSD's. 2 hours. Unreal.
