(This is BMP file type with transparent background colors black & white. want it in PNG? link here)[link]
Should work with most windows theme mod programs that support BMP or PNG.
(PNG 1 is a little better quality).
If your looking for a program to bring back windows 8 start menu & orb, (Classic Shell) is the only program i have tested it with.
Download Classic Shell here:[link]
this program works great with windows vista, 7, and windows 8
