I was cruising around the internet when I came across many users having issues with the visibility of the IE 10 and 11 scrollbar. I have noticed on some monitors and color combinations that the bar is sometimes difficult to see. So I fixed it up with some PowerShell. The script will change the IE scrollbar to the same color as your current theme color. Rerun the script after changing the color will update the scrollbar color. You will have to reopen any open IE windows after the script is ran to see the results.
