I have just been looking and twiddling under the bonnet, so to speak.
On 14/7/2017 I used a program twiddler called windows repair (Tweaking.com) and had a tweaking session, as you do.
Purpose;to sort out some of the mystery problems caused by W10 OS, items that with W7, Vista and good old Windows XP if I had any problems, I clearly knew where to look to solve whatever the problem was.
With W10 that is definately not the case, as current Microsoft policy being "Hide access to everything". Baffle em!
Amongst the tweaks, a large quantity of them, was a tweak that on shutdown and start-up, allowed me to see on screen, what Microsoft was up to. I have gone back into Tweaking.com and recovered the backup from the day I installed the tweaks and recovered the entry setup from that date.
Where as there appears to be a slight improvement on shutdown, it is nothing too substantial to shout home about.
I will keep looking and report back.
