Windows 11 provides two primary mechanisms for organizing screen real estate: Snap Layouts, accessed via the maximize button hover menu, and Snap Assist, which triggers a selection grid after a window is snapped to an edge.
In environments with ultra-wide monitors or multi-monitor arrays, the objective is to maintain a consistent, repeatable spatial organization for specific application groups. While Snap Layouts allow for intentional placement into predefined zones, Snap Assist focuses on filling the remaining void with available windows based on the current Z-order of the taskbar.
There is a trade-off between the precision of the layout menu and the speed of the dynamic grid when managing more than four active windows across different resolutions.

Because Snap Layouts lets you choose a predefined zone each time you need it, you can reproduce the same complex arrangement (e.g., three‑column on a 3440×1440 ultra‑wide plus a secondary 1080p screen) by simply invoking the menu again. Snap Assist, however, fills the remaining space based on the current Z‑order of windows, which can place an unintended application in a slot when you have more than four active windows or when you need a layout that isn’t half/quarter/full.
If the windows do not return to the exact zones, the feature lacks persistence; you would need to re‑apply the layout manually.
To confirm whether Snap Layouts is available on your system, please provide the Windows 11 version/build number (e.g., 22H2, 23H2). If the version is older than 22H2, Snap Layouts will not be present and Snap Assist will be the only option.
Use comments to ask for clarification. Post a solution as an answer.

When you pick a layout from the maximize‑button hover menu, Windows writes a binary blob to HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced (often named SnapLayouts). The blob ties the chosen zone index to the monitor’s device‑instance path and EDID, so if the monitor reconnects through the same port and its EDID stays unchanged, Windows can automatically re‑apply the layout.
Snap Assist builds its on‑screen suggestion grid from the taskbar’s MRU list. Background services, recently closed apps, or system timers can populate this list, causing unrelated windows to appear in the grid when you snap a window to an edge. In multi‑monitor or ultra‑wide setups this can introduce friction when you need a non‑standard split.
