Microsoft Camera Codec Pack (RAW and WIC)

Microsoft just released a RAW WIC (windows imaging codecs) codec pack. This means that any programs that uses WIC (Windows Explorer, MS Photo Viewer, etc..) should automagically be able to view RAW files.

It's available in 32 or 64 bit versions

I tested it and all .CR2 files are now viewable in Explorer.
