I have only just started to find my way around it,there is a start button which once clicked looks different to 8 with more options plus it also lists the apps and other features and I expect this can be added to,there does not appear to be the shut-down option from the start button,but the option appears at the top right of the page,again you may be able to modify this option.
Once rolling the install took around 10 mins which does seem a lot faster than previous versions of windows,and from my SSD it boots to the log in screen in about 15 seconds and once logged it it seems usable in another 15 seconds,I will try loading it on a ageing laptop that runs 7 okay to see how well it works on that
