Which codec in K-Lite enables yuv444p playback?

I have a file that plays in VLC, but not WMP. I require WMP playback. I know that K-Lite will enable playback, but I cannot install K-Lite because reasons. And so I'm trying to figure which specific codec is enabling playback of this file.

ffprobe output:

Code:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Test_H264_yuv444p_AAC_5760x1080_1fps.mp4':

Looks like h264 with yuv444p. I'm guessing it's the yuv444p bit that is tripping up WMP. Which codec in K-Lite enables yuv444p playback?

Thank-you!

You need a H264 decoder that supports Hi444.
And you need to configure Windows to use that decoder instead of the Microsoft decoder.

I can not share all the secret details, because reasons.
