The interface of Windows 10 makes extensive use of transient scrollbars. They can be found in UWP apps from the Microsoft Store, as well as in core UI components like the Start menu. These scrollbars are normally hidden and only appear when you move the mouse, then disappear after a few seconds.
How to Stop Scrollbars from Disappearing in Windows 10
Scrollbars that vanish save a few pixels on the screen but are confusing and difficult to use. If you’re tired of looking for invisible scrollbars or having to hover over them before they appear, keep reading to find out how to disable this behavior.
The option is controlled by a one-click setting in the Settings app; the hard part, as always with Windows 10, is finding it. Instead of being added to the Personalization category, the control is found in the Ease of Access section.
Click the “Ease of Access” tile in the Settings app. Look for the “Automatically hide scroll bars in Windows” toggle button under the “Simplify and personalize Windows” heading on the page that appears. Toggle the button to the “Off” position by clicking it.
You’re finished! The change will take effect immediately, and the Settings app’s own scrollbars will appear, as shown in the screenshot above. Wherever a scrollbar is present, it will now be permanently visible and ready to use. It’s a minor change, but one that you might find useful.
