If you are going to "Sleep it" - why "power off for the night"? I cannot reproduce your problem even with my SSD running W10 Pro 64bit Insider Preview version 1703 OS build 16232.1000. My SSD with W10 Pro 64bit version 1703 OS build 15063.413 works OK putting comp to sleep using KB button and leaving for 7 hours. It wakes when spacebar is pressed or mouse activated with all icons in place as normal. There must be some program/software that is waking your comp.
