None of the latest drivers for my ASUS P8P67-LE work in Win 10, including the Win8.1 drivers several internet message board posters claimed. Maybe they did a year ago, but no more, apparently. Not a big issue as everything is working reasonably well except for a bit of lag from my PCIe USB card. I'll see if the mfg's driver fixes that or buy a new card. Even a retired guy can afford that.
Installed and used Win10 for Tank Night last night and everything went great. Better then usual even.
Next for me is checking Skuzzy's list of telemetry things to disable, then transfering my Thunderbird and Firefox profiles (yeah, I never went with Pale Moon even though I think I should have. I was afraid for future support.)
Might sound like I'm done but I haven't even tried to install Office (2003) yet. Tons of programs and data still waiting for the all clear point.
For Denniss, as I said, that Nvidia link I posted delivered driver 419.35 for my MB using Win10. Oh! and it works great! Both my monitors are now set up properly with the Dell in portrait mode the same way I had it in Win7. I'm very happy. That link is highly recommended to anyone with grafic card problems. I just hope Win10 dosen't futs with it. I belive my install is your 1809 or whatever. According to the download site, they only distribute the latest version of Windows 10 including all the latest updates.
