Windows – How to change the color of the taskbar in Windows 10

The answer by @DavidPostill for changing "Menu" in "Personalization > Window Color and Appearance", does not apply if you are running the Aero theme. It needs the theme to be set to "Windows Classic". Not even "Windows Basic" will work.

If you want to change the menubar, you will need to hack Windows software using a resource editor or even a debugger. The only Windows software I know that might take part in the display is Shellstyle.dll, and it is not at all sure that it is the one that draws the menu bar.

An example of how such hacks are done can be found in the article :

However, you are on your own for discovering where the menubar colors are set.

But even if you do, your changes might render your computer unusable, since essential Windows components are digitally signed by Microsoft and are therefore unmodifiable. Even if you managed to hack Shellstyle.dll, the changes might be undone by the next Windows Update, so you may need to repeat them time and again.

Your real choices are really two : Use the "Windows Classic" theme, or accept the limitations of the Aero theme.
Anything else is playing Russian Roulette with the health of your computer.

I figured out how to change the taskbar text to white, which is what I came here hoping to find.

Go to personalization in the control panel and switch to the default theme called Windows. The text will be white. Then switch the background and color back to whatever they were before, and the text should stay white.
