Using the Zune remote control is as easy as changing a registry value. Now you will still need to have a IR receiver on your computer. If you already have a media center remote then you most likely have one. The plus to using the Zune remote is its simple layout. If you just want to pull up a playlist or watch a video it’s all the remote you need. The directions are below. Going into the registry can be dangerous. Probably want to make a backup before making changes.
Open the registry. Scroll down to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HidIr\Remotes\745a17a0-74d3-11d0-b6fe-00a0c90f57da
Find the REG_DWORD named CodeSetNum0 and change the value to Zero. Reboot the PC and enjoy.
