Well I finally decided to update my Windows 7 box to Windows 10. It was still free
from here so long as you already have an older version of WindowsNow I am customizing, and the black start button and other system icons were driving me crazy, as it was hard for me to see with my green taskbar. So I found out how to change them to white.
Go to Personalization -> Colors
Under Choose Your Color, set to Custom, then:
Choose your default Windows mode = Dark
Choose your default app mode = Light
Transparency Effects = On
Pick your accent color below
Show accent color on the following surfaces
Start, taskbar, and action center = On
Title bars and windows borders = On
Note, the Start, taskbar, and action center box will be grayed out unless you set Color to Dark or Custom.
If you like the Dark option, you don't need to set your Color ot Custom, just go Dark.
