Is it possible to customize Windows 8.1 colors similarly to how it was since Win95 in the "Advanced Appearance Settings"?

Solution 1:

The Advanced Appearance Settings dialog was removed in Windows 8, but there is a 3rd party replacement

But for the default Windows Theme, changing color is not supported since Vista.

Solution 2:

You could download Winaero Tweaker. It lets you adjust most of the advanced appearance parameters that still work with modern Windows theme.
