Hi there
@WXC
If you can create a short cut to the item you can in properties select icon - you can use your own .ico files -- they have to be standard size. For those that are embedded in the dll files the easiest way would be to capture the icon image via snipping tool or whatever as a png - then use icofx program to convert to ico and then use that icon in your system. Not sure though for those "new" type of tiled apps though or those that don't have an easy "findable" folder on your system.
For icofx - last free version -- perfectly good enough for this :
You can design your own ones too.
I would strongly advise against messing around with dll files especially across different OS'es. !!
