Turn On or Off Scroll Inactive Windows in Windows PC
Windows includes a built-in feature to let you scroll inactive windows by just hovering over them with the mouse pointer without your currently active window losing focus. This feature can be very useful when you are multitasking or having multiple windows opened at a same time. By hovering over an inactive window and scrolling the mouse wheel, you can scroll that window up and down even without clicking on it. Thus, without losing control of the active window, you can access the required information from the inactive window. But, Although the ability to scroll inactive windows can come in handy in most cases, some people may not like it. Note that this feature is enabled by default in Windows 11. In this article, we’ll show you how to enable or disable this feature in Windows.
