I am considering porting some of my favorite vector based icon sets to Windows, and was hoping to include support for Windows 8. Has Windows 8 changed the icon set format? Can I use SVG for my desktop icons?
Windows icons are still raster images. I believe InterfaceFormallyKnownAsMetro tiles can take SVG images though.
In application icons can be whatever the application framework handles and is largely independant of the operating system.
