The Snap Assist Annoyance
Windows 11 includes a feature known as “Snap Assist,” which is an evolution of the Aero Snap feature introduced years ago. When you click and drag a window by its title bar and push your mouse pointer against the top edge of your screen, Windows assumes you want to focus entirely on that application and automatically maximizes the window to fill the entire display. Similarly, dragging to the sides snaps the window to fill half the screen. While this is great for productivity, it is incredibly irritating if you use a large 4K monitor or an ultrawide display and are simply trying to move a small window near the top edge of the screen without wanting it to explode in size.
How to Disable Drag-to-Maximize
You can turn off this automatic resizing behavior entirely within the Windows 11 Settings app, allowing you to move windows freely without them snapping to the edges.
1. Click the Start button and select the gear icon to open Settings (or press Windows Key + I).
2. In the left-hand navigation sidebar, click on System.
3. In the main pane, click on Multitasking.
4. Look for the main category labelled Snap windows.
5. You can toggle the master switch for “Snap windows” to Off. This completely disables all snapping behaviors, including dragging to the top to maximize and dragging to the sides to split the screen.
How to Disable Only the Maximization Feature via Registry
If you like side-by-side snapping but specifically hate the drag-to-top maximization, the Settings menu doesn’t offer a granular toggle. You must disable a specific mouse behavior in the Control Panel.
1. Click the Start button, type Control Panel, and press Enter.
2. Change the “View by” setting in the top right to Large icons.
3. Click on Ease of Access Center.
4. Click on Make the mouse easier to use.
5. Scroll down to the section labelled “Make it easier to manage windows.”
6. Check the box next to Prevent windows from being automatically arranged when moved to the edge of the screen.
7. Click Apply and then OK.
This setting stops the aggressive drag-to-maximize behavior, allowing you to freely position floating windows at the very top of your display.
