Took a long time coming, this, but Windows now finally has background scrolling. This handy feature basically allows you to scroll inactive windows when you hover over them.
Quite a timesaving option if you are a power user, or using your Windows 10 system for professional work, and dealing with multiple open windows at the same time. The feature is automatically enabled by default, but if not, then you can turn it on in Settings.
This short tutorial will show you how you can enable or disable background scrolling in Windows 10.
1. Open Settings.
2. Go to Devices, and then click on Mouse in the left side of the panel.
3. The Scroll inactive windows when I hover over them toggle option is the one you are looking for. Simply move the switch to however you would like things, and hit the close button.
You will now be able to scroll through documents, webpages and other open files, even when their window is not active.
