If you frequently read audiobooks, you may sometimes want an M4B player on your Windows. It is annoying when you can't open these M4B format files on Windows. M4B (.m4b), a file extension for MPEG-4 files, is commonly seen in audiobooks downloaded from iTunes. Normally M4B files can be opened by common media players like Windows Media Player. One exception is that some M4B files are protected by DRM encryption in case of digital piracy, which will need special authorized devices for M4B playback. But this is not the only case. In the next part, we will tell you two situations to help you play M4B on Windows10/8.1/7 instead of a special M4B player.
Part 1. Why Your Computer Cannot Open DRM-free M4B Files
When you try to open M4B files on your Windows computer, you may receive a popup message saying that they can't open such a file because it doesn't recognize the file extension. Generally, in such case, there is nothing wrong with the M4B files, but simply because your computer fails to interpret this special format and then makes the false response.
This interpretation failure can be easily solved with Windows Media Player. Click right on the file and choose "Open with". Then your computer will suggest a list of supportable programs to open M4B files. Choose Windows Media Player here. If you can't find it here, it is ok to "choose default program". Next, it will pop up a dialogue box telling your computer can't recognize this file. Ignore the reminder and tick "OK" to go on. Then the file will be opened smoothly. This way is true of any other media player on your computer.
Part 2. How to Play DRM-protected M4B Files on Windows Computer
Once M4B files are encrypted by DRM, they are only playable on some special DRM-authorized devices like Apple iTunes. That's why you cannot use Windows Media Player to open them. Under the current conditions, you need to install a special M4B player on your Win 10, or alternatively free M4B files from the obstruction of DRM. Here you can adopt a practical application, TuneFab Audiobook Converter to achieve this goal.
