Stop the snap layouts pop-up when hovering the maximise button — via Winaero

The easy way

1. The easy way: Settings → System → Multitasking → Snap windows → untick Show snap layouts when I hover over a window's maximize button.

Registry change

Double-click a .reg file and confirm to merge it. Right-click → Edit first if you want to read it, which is always a good idea with any .reg file from the internet.

Apply

Windows Registry Editor Version 5.00

; Oddbyte.Me: Stop the snap layouts pop-up when hovering the maximise button

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"EnableSnapAssistFlyout"=dword:00000000

Undo

Windows Registry Editor Version 5.00

; Oddbyte.Me: undo Stop the snap layouts pop-up when hovering the maximise button

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"EnableSnapAssistFlyout"=dword:00000001

Same thing from a command prompt

Run in a normal (non-admin) Command Prompt or Terminal.

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "EnableSnapAssistFlyout" /t REG_DWORD /d 0 /f

Undo:

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "EnableSnapAssistFlyout" /t REG_DWORD /d 1 /f

The Settings change applies immediately; the registry route needs a sign-out or restart.
