i installed it recently because of some reasons and it has just the same dpc latency value and drivers with high latency count
i submitted that report for confirmation of 'did i perform it right?'
and nevermind about it. as i said before, i'll clean install os soon :smile9:

one of two test files is only 500mb even after unzip
maybe you can run this one on your laptop

i didn't test win7 on this computer yet. and i don't want to because as you know windows 7 dosen't support many uefi features so it runs on csm legacy mode
so i can't use fast boot and many more, plus even some chipsets of my z170 mother board dosen't support win7 
(
well.. then i'll try it for test though..
and my old fx8300 computer had an issue with win7 too
