Time to post initial impressions.. after first day.
This build is looking very good for now . Faster boot and wake up from sleep is still here, but memory usage went down from 14291 build, which was something higher.
MS fixed Snipping tool issue, for what I would like to say thanks straight to the person who did it , (not that we haven't had some fun over it, but we surely did make a lot of noise, so the MS heard us).
So far, I would recommend this build even for slow ring.
