I got two machines running Win10, both with on board video.
With the AMD chip it doesn't like being run through a KVM, at my preferred setting, lower than what it suggests, and messes up the desktop layout, both icons and windows, when I switch to it.
On an Intel video chip machine, direct HDMI connected, on boot, same damn thing with icon layout because of the more vision-saving sizing, I'm guessing.
Both machines worked fine before the updates.
I'm not the help desk, LOL.
Actually, I noticed some driver problems after this last 1607 update, but they were minor. I sometimes play a full-screen video game, and I used to be able to Alt-Tab out of it to the desk top, come back, and play some more. But, now, the video on the game is in slow motion (low frame rate) unless I stop and restart the game. The game is Doom 4; the video card is an Nvidia 970GTX in a big laptop.
I figure it will get fixed, eventually, either by MSFT or Nvidia. Maybe a buffer or video memory needs flushing.
Oh well, the cost of progress.
