Yesterday I changed the "Glass color" on my OS where instead of being blue it was black. There used to be a little section in the control panel where you could change the color and stuff but now it's disappeared and my taskbar and windows have gone back to the default blue color. How do I change the color back?

Right click on the desktop, click "personalize" and if the right window pops up click on "window color"

Hope that helps

That happened to me once. My little brother messed around with something and my toolbar at the bottom of the screen, turned pure baby blue. It was literally impossible to change the color. Eventually I fixed it somehow. I forgot how though. :3

I just click an Aero theme and customize it. There may be a different way to enable Aero, but I don't know of it.

Tried that.

Anyways I figured it out. Turns out I accidentally changed the theme from Windows 7 to a custom theme and the glass color changer wasnt supported for custom themes. It works now that I changed the theme back to Windows 7.
