Ok finally up and running latest build 10162.. after post update thrashing of my hard disk has settled... I can finally start poking around. Off the bat there is definitely speed improvement in this build. I'm using an older Dell latitude E5500 with intel core 2 duo and 4 gigs of ram. Its even smoother than build 10159, which in itself was pretty good. Other new additions, which are new to me, are my wallpaper. In a previous build (10158 to be exact)I've set the Hero image as my wallpaper. Yet for each of the subsequent build updates, the scaling of the wallpaper was thrown way off. I had to go manually reset my wallpaper back to a suitable resolution akin to my screen. I understand that there are multiple resolutions available in these builds, so as to suit different screen sizes. I understand that the OS is supposed to match a suitable resolution to the hardware on the computer its running on. Minor bug, very minor annoyance.. still dabbling around. Will report further findings as I uncover them.
