You can right-click on open desktop and click on PERSONALIZE. Under the 1st heading it says: Window Color and Appearance.
It says you can change the color of the TASKBAR in here.
You can change colors on many things in there, but I couldn't find where to change the Taskbar color.
And I also have no clue how to increase the icon sizes in the Taskbar, as well.
I know about UNLOCKING the Taskbar so you can increase it's width using the double arrow. I can do that, but I figured the icons would increase in size along with the Taskbar width; but NOPE - not to be.
Please Help, all.
