Sorry for not giving a clear response before.
Yes, in Windows: Settings: Personalization: Colors settings, the "Choose Your Color: Light/Dark/Custom" was the issue. The Windows update had apparently reset some stuff and unchecked the box at the bottom that says,
Show accent color on the following surfaces:
Start, taskbar, and action center
Title bars and window colors
I wasn't able to select "Start, taskbar, and action center" without FIRST setting the "Choose your color" setting to either Dark or Custom. Having it set to Light disables the checkbox on the "Start, taskbar, and action center" accent color option. So I changed the "Choose your color" to Custom and then I was able to select the option to show my accent color on the Start, taskbar, and action center.
Sheesh, it takes a lot of specific typing to explain this stuff, lol.
Thanks a lot for your suggestion. It really was a huge help to me. [e digicons]:thumbsup:[/e]
