On Skylake you have no OS limitations so you can bench everything on Win10. On other platforms someone can report you if you use Win 8.1/10 in some benchmarks. Don't worry about that as many people are reporting others just because someone was better than them. Some are weird to the point that if they can't beat you then for sure you are cheating
Just have fun and bench everything regardless how many points you can get. Even if you get 0.1 hardware points if you are the only one in the team on that hardware/benchmark then team gets points ( sometimes 2+ ) and you get Team Power Points too.
One more thing. You can run some benchmarks on a smart phone/tablet which is based on ARM CPU. If you have something then try hwbot prime. I don't remember if there is something else.
If you have CPU with IGP then you can run CPU max clock, reference clock ( FSB/bclk if motherboard is in the database ), graphics tests on IGP and CPU tests. Like every Skylake has IGP ... simply use it.
Trying various settings you will also learn where memory is helping or where you can use 1-2 cores or maybe more. Too many things to talk about now so if you have any questions then don't hesitate to ask them.
