K-Lite is said to contain adware or malware. The installed codecs might also mess up systems
there was a nice thread about thumbnails on windows:

In short the recommendation is to install ICAROS:
It only generates thumbnails and comes without adware.
- download / install
- activate (thumbnail generation) during installation or afterwards
- add "mov" to the file type list in the Icaros thumbnailing control panel.
- thumbnails are generated if you open any folder containing DXV .movs
