As to if this is true or not I do t know. He said once he deleted the entire section on the class tab of Regedit and imported his first code (whatever the first code is) fixed 80% of the issues.. For one you would need to reinstall new drivers unless windows 10 automatically reinstalled them, probably the former. I think this guy may have had a bad driver and that’s it, nothing outlandish like what I have, I mean all the newly built PCs I’ve made along with a few company bought ones and the latest one being a laptop, I just don’t see a driver being the issue, I mean you think it would be more widespread if that were the case, I don’t know..
I could try deleting some regedit like this guy on one of my rigs, can just reset it if things go awry...
