Vista was 32 bit. I'm using 64 bit 7. Under Vista I had the hotstart buttons linked to Firefox, Media Player, and WMC just by linking them to their respective .exe's. In 7 they only seem to work when pointed at WMC + whatever switch.
Right now I have the "=>" to just power up and go to the main WMC page, for the "music" I'm using the /directmedia: music /playallmusic and /nostartupanimation switches to have all my music start playing at the touch of one button (gotta add a open minimized command in there, does it have one?) which is very handy, and "DVD" uses the /directmedia: playdisk switch which is useless since I never actually have a disk in there lol. I'd like to link it to the new internet TV function, more specifically the listing/guide, but haven't figured out how to do that one yet.
