Apparently, this setting used to exist, not unlike how I remembered it. See this article by Windows Latest
But according to rumors it seem like MS want to axe it
And it seems like they did, since now this setting is gone
But they didn't remove this feature (?)
It's so weird. I remember enabling this setting when I was setting my laptop up (literally less than a month ago)
and now I realize it's not as cool as it sounds.
Further intrigue rises from the fact that my registry doesn't have this key in the registry altogether.
You should be able to change it via Group Policy client, however, and it might not need administrative rights.
It's under "User Configuration" > "Administrative Templates" > "Desktop", and it's called "Turn off Aero Shake window minimizing mouse gesture".
