XMedia Recode is a free Windows-based audio and video transcoding program. Compared to the well-known HandBrake, it provides audio conversion/extraction, audio CD rip, more editing features and a wide array of predefined presets, etc. If you're new to XMedia Recode, I'll walk you through the detailed steps of XMedia Recode MKV to MP4 conversion process.

Step 2. Run XMedia Recode, click on "Open File" button, locate the folder where stores the MKV video, select it and press "Open" to import it to XMedia Recode. There is a more convenient way, just drag and drop the MKV file into the interface.
Step 3. XMedia Recode will list the MKV video with Name, Chapters, Duration, Video/Audio Streams and Subtitle Tracks. Under "Format" tab, select "MP4" in the drop-down list of "Format" and "File Extension" respectively. You can also select "MP4 (stream copy)" option to remux MKV to MP4 without re-encoding, and make a web-optimized faststart MP4 file.
Optional. For further editing requirement, switch to each tab, where you're able to change video/audio codecs, add or remove subtitles from MKV, cut and crop video, edit video chapters, normalize audio, customize ID3 tag, etc.

Lastly, click on "Add to queue" button, and then press "Encode" to make XMedia Recode convert MKV to MP4.
