I had this exact same issue with my work machine and my at home workstation. Wifi adapter completely broken, I tried to revert back to Windows 8 on my work machine and it gets stuck on a black screen for over 24 hours. I tried to power down to restart it but no luck. Somehow everything got corrupted. Had to completely reformat the drive and install the operating system all over again, which it then proceeded to upgrade straight to Windows 10 again. I lost months of work but was able to recover from a backup I had a week prior to the incident. Absolutely disgusting business practice by Microsoft. The only times where a Windows 10 installation has worked well for me is when it's a brand new machine with little to no extra content on top of the existing OS. If you've used Windows 7 or 8 for over a year and accumulated a fair amount of apps, files, content, I can almost guarantee you're going to run into something breaking after the update.

Same scenario three weeks ago trying to help out my brother on his brand new Asus that came with Win 10. The wireless hardware just disappeared from the control panel so the option to update the driver wasn't available. I was about to walk him through a complete OS re-install with the option to keep his files until he decided that a wired connection was OK. At the time there was almost no available recent support articles on this issue, but I'm starting to think a Win update caused this after seeing others with the same problem. And here he was going to blame it on his kids...

I installed a fresh Win10 for a family member, and the complete mess of absent/hidden/redesigned/half-duplicated control panel stuff was my first hint that I'd want to stay on Windows-7.

Same issue here. I actually upgraded to Win 10 from Win 7 about 3 months ago. Then 3 weeks back, an automatic update, and lost both Wifi and Wired connectivity. - No use updating drivers (they are not available for Win 10). -Cannot go back to Win 7 from System Update (since that option available only for a month). -Since Win7 is pre-installed, cannot even download a CSO image file with my product key!

I am still lost about what to do. Thankfully, after a complete restore to first Win10, I have wired connectivity back.
