Windows Journal

Windows Journal was a note-taking application that was initially introduced in Windows XP Tablet PC Edition. It allowed the user to create and organize handwritten notes and drawings and save them as .JNT files or export them as TIFF files. It was designed to be used on Tablet PCs and graphics tablets using a stylus but, it could also be used with an computer mouse.

.JNT files could also be viewed using Windows Journal Viewer on other systems that did not have Windows Journal.

Windows Journal was discontinued and removed from the OS in Windows 10 Anniversary Update in favor of OneNote. In July 2016, Microsoft released a patch (KB3170735) for Windows 7 and Windows 8.1 to notify users about future Windows Journal developments. A month later, Microsoft released another patch (KB3161102) to remove Windows Journal from Windows 7 and Windows 8.1 after it was discovered that the Windows Journal file format (Journal Note File, or .JNT) was susceptible to security exploits.
