Last week Windows10 attempted to update the graphics driver on my computer and failed with this error 0x800705b4. When I rebooted my PC over the weekend I noticed that my graphics resolution had gone down and changed it back to my usual resolution.
Then, when playing a browser game, I noticed how slow it was and checked a bit closer my display settings. Apparently my NVIDIA GeForce 9600 GT driver had been replaced by some Microsoft Basic Display Driver; see also this discussion.
I visited NVIDIAs web site for driver downloads ( German site in my case ) and first let it detect my installed graphics hardware. Before that worked okay I had to upgrade my Java. Finally NVIDIA correctly detected my graphics hardware and offered me the correct driver download. Everything back to normal now, after roughly one hour wasted and two reboots.
Dear Microsoft, how about the following: when you fail to upgrade software on my computer, can you please leave it like it was before instead of installing some different software without my permission ?
