How to Turn On or Off Snap Windows in Windows 10

Windows 10 Snap Assist is a useful productivity enhancer for most people. Rather than fiddling around to get windows the exact right size, it lets you drag one to the side or corner of your screen and automatically snaps windows to half or quarter of your screen. If an application is already open on part of the screen, additional Windows snap features fill the remaining space instead.

Problems with Snap Assist

Unfortunately, the feature, previously known as Aero Snap, just gets in the way for some people. Users find that they accidentally activate Snap Assist when moving between monitors. Others find that the Windows snap tool simply isn’t useful for them when they have third-party software like PowerToys for window management.

As a result, we’re going to show you how to turn Windows snap on or off at will to suit your preferences. You can use the settings app, legacy control panel, or Regedit to do so, depending on what you’re most comfortable with. We’ll also show how to adjust three individual settings – automatic sizing to fill space, suggestions of what to snap next to a window, and automatic resizing of an adjacent window once snapped.
