MKV Optimizer removes unnecessary audio tracks from selected MKV files. And that too automatically. Likewise, soundtracks can be recoded. To edit the MKV files MKVToolNix is needed. MKV Optimizer automatically searches for MKVToolNix in the MKV Optimizer folder as well as under the "Program Files" or "Program Files (x86)" folder. If MKVToolNix can not be found, the path can be specified manually. For the recoding of the sound tracks the program ffmpeg is needed. The corresponding executable file is simply copied to the folder of the MKV Optimizer. Requires MKVToolnix!

The program is self-explanatory so far. The folder to be searched can either be entered directly into the upper text field, dragged onto the text field or saved by clicking on the button with the three dots.
By default, all subfolders are always searched and only those files that have more than one audio track are considered.
If the path to MKVToolNix has been specified after the "Settings" tab, clicking on the "Search" button searches and displays all files in the specified folder.
In the field "Keep audio tracks with the following [language]" all found audio tracks are displayed. If you do not want an identifier (language), simply delete it from the field. If a MKV file has several identical audio tracks (GER (AC3), GER (DTS)), these can be filtered via the "Accept only the following audio codecs" field
If you select track ID, you can specify the appropriate ID for the respective track. The values are always separated by a comma.
The same procedure applies to subtitles,
With a double-click on the file, the GUI of MKVMerge is called.
In the list itself, the files to be converted are ticked. A context menu to mark all files is also available.
After selecting the MKV files and the desired sound tracks or subtitles, clicking on the "Convert" button triggers the conversion process. It is calculated per file as well as for the whole process how long it takes.
Audio conversion
The folder to be searched can either be entered directly into the upper text field, dragged onto the text field or saved by clicking on the button with the three dots.
In the profile field already deposited profiles can be used for the conversion of the soundtracks. If you want, you can also create your own profiles. The program ffmpeg is needed for the conversion. The output file is located in the same folder as the source file, but the file name can be adjusted via the profile settings.

Issue solved, I fixed the issue by right clicking and going to compatability settings > Change high DPI settings > checked the box for Program DPI to fix scaling issues > Selected 'I open this program' > Checked the box for Overriding high DPI scalling behaviour > Selected 'System'.
Now the program boots perfectly.
Thank you from Mum and Dad.

The program works fine except that on Windows 10 with 4K resolution the program does not display properly. Everything has lost all of its design layout formatting so text is half off the screen or tab buttons are out of place so cannot be pressed.

It worked very well, makes removing unwanted languages to save space a snap. However I really wish there was an option to simply change the default audio track without actually deleting any of them. MKVToolnix can do it easily however it's a huge amount of work to through every single file doing it that way. It seems like it would be a simple option to add.
A minor correction, in settings where it says "Always maintained following languages" it should say "Always maintain the following languages. Also the word Automatically is misspelled. Just nitpicking though. :)

Great Idea, really helpful, however i get constant crashes, doesn't like network drives, doesn't like the network period.
it processes one file then always crashes when it goes to start the next.
when i load the program sometimes it sees my network drives, other times it doesn't. for me it's quite unstable, not sure why?

Great MKV tool. Was working fine until I set my PC resolution to 4K and the whole interface squashed up.
