If you are looking for information about Windows Image Component (WIC), we recommend to read the Wikipedia article.
If you have a DSLR digital camera such as Canon, Nikon, Sony, Panasonic and you are shooting in RAW format, an appropriate WIC codec is required to read those RAW files.
You can check with your camera manufacturer if they offer a codec for your model.
As a simple solution we recommend the Fast Picture Viewer Codec, which will not only allow you to read most RAW files, but also to optimize read speed and image orientation of JPEG thumbnails in Windows.
Buy FastPicture Viewer WIC Codec, which will read most photo formats and also fix the JPEG rotation in thumb view of Windows Explorer. Supports all Windows versions from Windows XP SP3 to Windows 10 (32 and 64 bit).
Windows 10: Raw Image Extension from Microsoft adds support for images captured in raw file formats by many digital DSLR cameras. Requires Windows 10 May 2019 Update (version 1903) or later.
Windows 7: Microsoft Camera Codec Pack is a free alternative from Microsoft to support digital camera formats (such as Canon, Nikon, Panasonic, Sony etc.) in your photo editing software. Supports Windows 7 and Vista (SP2).
