Good news for photographers, Microsoft has released a pack for Windows 7 and Windows Vista RAW format support.
Specifically, it is (finally) to view thumbnails of photos taken in RAW format under the Windows Explorer and Windows Live Photo Gallery. Some manufacturers already proposed plugins for viewing the RAW in Windows Explorer, but the latter often limited to a single model of aircraft. Now, the pack made available by Microsoft is able to support the RAW files from most of the NPA in the market (more than 120 models to this day). The detailed list is available on the Microsoft site.
To benefit from this new feature, just download available on this page Codec pack.
