I'm not sure, but Windows 10 minimizing all currently open windows when you drag a window to left and right has to be the worst feature.
Sometimes I love to arrange the windows properly to make work better on a multi-display environment. As nerds at Microsoft read me adjusting the window position as "shaking" they decide to minimize all of my open ones. Since today, I've been looking hard both left and right, but found no actual use for this "feature" (bug). The gesture guessing is inaccurate at best. Also, IF (emphasis on if) I want to minimize all of my currently open windows, I'd love to clearly indicate the wish for doing so. I hate these artificial stupidity systems which try to out-smart me. They never do.
If you're like me and want nothing to hear from that, there is no actual option for getting rid of the madness. The ONLY option seems to be to edit registry, so let's do that.
Registry-file is very trivial:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"DisallowShaking"=dword:00000001
Import that and you're done. For further info, read article How to Enable or Disable Aero Shake in Windows 10 @ TenForums.
