Stock Windows 8.1 Start Menu Icon

I feel like I'm missing something really obvious, but is there a way to get the stock Windows 8.1 Start Menu icon back?  I'm not a huge fan of the Start8 icon, and would prefer a completely stock look to the icon.  I do see that you can use your own image, so alternatively perhaps someone can point me to how I would go about getting the actual Windows 8 Start Menu icon to use there.  

Thanks!
