Is there a way to increase scroll bar contrast in Windows 10?

Well this question is exactly what is says on the tin: Is there a way to increase scroll bar contrast in Windows 10?

Since it seems that it's again modern to hide settings as much as possible, I was wondering if there's maybe a hidden option to change scroll bar contrast somewhere.

Solution 1:

The only way I know of increasing the contrast of scrollbars in Windows 10 is:

Settings -> Ease-Of-Access -> Color-&-High-Contrast -> High-Contrast

and change the setting from "None" to one of the four listed high-contrast themes. That will, unfortunately, make massive changes to all elements of all windows, not just scrollbars. But it will make your scrollbars higher-contrast.
