This works exists in Windows 10, Windows 8 and Windows 7.

While it is easy to disable the Snap features via Ease of Access Center, there is no option there to turn off its specific options. Turning off the Snap disables the following:

  • drag-to-top to maximize,
  • drag-from-maximize to restore,
  • drag-to-side-edges to snap
  • vertical maximize

So it’s an all or none switch. You might want to keep Snap  and only disable the vertical maximize option. This post will show you how to achieve that.
