I’ve recently upgraded my home lab from running Windows 8.1 to running Windows 10. It wasn’t an inplace upgrade, as I replaced the OS drive so it was a fresh install onto an SSD, all was going swimmingly until i hit an issue with Windows Update replacing some of my drivers.
While the initial installation went ok, Windows Update ran and patched without a hitch. I then spent some time putting on the latest vendor drivers from Asus for the motherboard and AMD for the graphics card. The system ran perfectly for a couple of days until the next round of Windows Updates. After that Internet connectivity was intermittent, pings were dropping left, right and center making remote access impossible. On further investigation the network card driver had reverted from my Intel 82579LM to a Microsoft driver!
Well after unisnstalling the Microsoft driver, a scan for hardware changes and reinstalling the network card driver, the system was working well again, but I wanted to stop Windows Update from installing drivers for me in future.
