Windows 10, Explorer.exe is causing performance issues on your PC.
TL;DR: I fixed this issue by disabling the automatic color change of windows title bars to match the (slideshow) background image. To see if this affects you, try opening several windows (the more there are open, the more dramatic the stutter will be). Then, change the color of windows title bars on the Windows control panel. If you experience a dramatic stutter, that's it. Just choose a color and disable the automatic color changer. I found it when noted that some people were disabling the background slideshow, which to me made little sense. But the color change of all windows probably forces the OS to reinstantiate all windows, including the ones that are not visible. To a programmer, this is a typical (and nooby) error that causes severe performance issues. People are also noting that the existence of a corrupt PDF file on the workspace may cause these symptoms. Easy to check out. To finish, never start your troubleshooting process by a drastic measure like downgrading or reinstalling drivers, apps or even the entire OS. You wouldn't believe that this PC which is my daily driver was last clean installed back 10 years ago with Windows XP and was upgraded to every Windows version until this one (W10) including Vista. Also, like the Ship of Theseus, all of its hardware was upgraded, except the original HD that today is used only as a backup. And it can run Microsoft Flight Simulator (haven't tried Crysys - not my style).
I've been trying to resolve this odd problem, filing several tickets at work. When the IT team took over my computer, they changed all the backgrounds to black, which resolved the issue. The backgrounds are still shifting, but disabling the automatic color change fixed it! It's been really frustrating. You shared this solution in a thread almost two years ago, and it helped! Thanks so much!
