Photo Mosaic Software.

I need a recommendation for a free, offline Photo Mosaic program for Windows 7 and newer. Searching I found a few but they are either commercial, outdated, online and/or not for Windows.
I want to recreate an image using multiple small images like the image in the link.

I recently downloaded a Japanese Adult Video (JAV) that had been "uncensored" by removing the Mosaic (MR).
Is there a free, simple to use, program that I could use to Remove the Mosaic of a censored JAV?
Doing a search I found VSDC Free Video Software that seemed that the only free thing was the download, it implied but never mentioned the amount of a monthly fee and it appeared to be extremely complicated, claiming it could do all kinds of things to improve your videos and didn't mention Mosaic Removal specifically.
I don't need to "do all kinds of things" to improve a censored JAV. I just want to Remove the Mosaic (MR) to make it uncensored.
Any recommendation would be appreciated, Eldon. You have helped me a lot in the past.

 

Eldon hasn't been seen since July 2023. We have no idea what happened to him.
And that post is from 2017! That's a long time when you are discussing computer software.
