Aero Shake is a window management feature in Windows that allows quickly minimizing all open windows by 'shaking' the app you want to keep active. It will remain open on Desktop, and all other windows will be minimized down to the taskbar. The option to disable is not anywhere in the GUI. However, Microsoft is working to change it.
To disable or re-enable the disabled Aero Shake feature, you need to edit the Registry. I have a tutorial on this here:
In fact, there are some tools that provide a GUI for that. For example, Winaero Tweaker has such a checkbox.
However, the good news is that a native option to enable or disable Aero Shake is coming to Windows 10. It will be available on the Multitasking page in Settings. The development is just started, so there is no working option yet, but there is already a placeholder.
Aero Shake was part of the Windows Aero interface that has long been outdated. In Windows 7, Microsoft introduced two new ways to arrange windows and manage their size/position and window state. The two features are called "Aero Snap" and "Aero Shake" respectively. The Aero Snap feature arranges and resizes windows by moving them to the left, top or right edge of the screen. The second one, Aero Shake, allows you to minimize all open apps when you shake the active window.
Some Windows 10 users prefer to keep Aero Shake disabled because it is easy to accidentally move a window and get others minimized.
Winaero greatly relies on your support. You can help the site keep bringing you interesting and useful content and software by using these options:
