Image Capture saves in the default .jp2 format how to convert in Windows 7

I was helping a client today who used his scanner connected to his mac and used Image Capture to save the scan. He then copied the file over to his pc to make it work with his corporate system. When he was on his Windows 7 computer, there didn’t seem to be a default or installed utility that would open up .jp2 files. After some research it turns out that Photoshop, Infranview, XnView can open them on the PC.
Its a times like these with simple cross platform struggles, that I wish that Microsoft and Apple would combine forces.
