Re: Windows 10 -- why so broken?
I have a similar problem when I use either 7 or 10 and connect my tv using HDMI. The easiest solution is to just reboot after disconnecting the VGA cable from the primary monitor.
I was trying to figure out what driver was causing the issue but the I switched to using mostly Mint. Now I simply connect whatever monitors I want on the fly and it just works. KB3086255 was the best update ever since it forced me to stop updating and pick another OS to use online. For now I disconnect the router before I play the older games I paid good money for. When this machine dies I'll try to find one that runs everything I use but I know that won't be with windows.
