Snap Layouts, introduced in Windows 11, took the old Windows 10 window-snapping feature and made it dramatically more discoverable and flexible — a genuinely useful productivity feature that’s easy to underuse if you don’t know it’s there.
Hover over a window's maximize button to see layout options, OR: Win + Z - opens the snap layout picker directly from the keyboard Win + Left/Right - classic half-screen snap (still works) Win + Left, then Up - snaps to a quarter of the screen
Snap Groups
Once windows are snapped together, hovering over any one of them in the taskbar shows the whole group as a thumbnail — clicking it restores the entire arrangement at once, genuinely useful for a multi-window workflow you return to repeatedly throughout the day.
Multi-Monitor Behavior
Settings > System > Multitasking has a toggle for whether Snap remembers window arrangements when a monitor is disconnected and reconnected — worth checking if windows seem to “forget” their snapped position after undocking a laptop, since this specific setting is exactly what controls that behavior.
