My new Windows 8 Start Orb based off of Microsoft's new Windows 8 logo styled in a Metro UI-like style.
Hope you like it!
To change the Windows 7 start orb, I recommend you download Windows 7 Start Button Changer v2.6 here: [link]
P.S. If, for some reason the alignment of the orb looks "off" to you, it is not, it is just an illusion, zoom in and find out it is completely and accurately aligned (and has been TESTED!)
There should be a green down arrow on the right side of the page.. If you do not see it, you are possibly experiencing a common bug that prevents it from showing up. my advice is to either try a different browser or keep refreshing the page until it shows up, sorry...
I have no idea considering the start orb does not exist on Windows 8, but if you try programs like Start8, StartisBack, Vistart, or Classic Shell, there are ways to change the style and get the Start Menu back.
