How to Fix Snap Layouts Not Working in Windows 11

The Problem

Windows 11 Snap layouts should appear when you hover the maximize button or press Win + Z—but nothing pops up, or windows only maximize full screen. Snap Assist groups windows into tiles; when it breaks, multitasking feels like Windows 10 without Aero Snap.

Whole taskbar broken? See taskbar not working if maximize hover and Start both fail.

Symptoms

  • No layout flyout on maximize hover.
  • Win + Arrow snaps to half screen but Win + Z does nothing.
  • Snap broke after a display scaling or multi-monitor change.

The Fix: Step-by-Step

Step 1: Enable Snap Settings

  1. Settings → System → Multitasking.
  2. Turn On all Snap windows options (show snap layouts, snap windows when I drag to top, etc.).
  3. Toggle Show snap layouts when I hover over a window's maximize button specifically.

Step 2: Use Keyboard and Drag Gestures

  1. Press Win + Z on a focused window to open layouts manually.
  2. Drag a window title bar to the top of the screen to maximize, or to left/right edges for half snap.
  3. On small screens, layouts may hide—rotate to landscape on tablets or lower scaling temporarily.

Step 3: Display Scaling and Multiple Monitors

  1. Settings → System → Display → try 100% or 125% scaling—extreme custom scales break hit-testing on maximize.
  2. Identify monitors and set main display where you use Snap most.
  3. If a second monitor was disconnected, reboot once—ghost display configs confuse snap zones. See second monitor not detected.

Step 4: Restart Explorer and Install Updates

  1. Ctrl + Shift + Esc → Windows Explorer → Restart.
  2. Install Windows Update—Snap is part of shell; cumulative updates fix known bugs.
  3. Sign out and back in if Explorer restart is not enough.

Step 5: Third-Party Tools and Registry (Careful)

  1. Uninstall or disable PowerToys FancyZones temporarily—conflicts mimic “Snap broken.”
  2. Avoid random “Windows 11 tweakers” that disable snap via registry—re-enable multitasking in Settings first.
  3. If you used a debloat script, review debloat Windows 11 and re-enable shell features you still need.

Step 6: Repair System Files and Profile

  1. Admin terminal: 
    sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
  2. Test Snap on a new user account—broken profiles lose shell handlers.
  3. Widgets and Snap share taskbar shell—if both fail, also try Widgets not working.
