It's a real composed puzzle, not a chess.com concoction. It might have won a prize in a composition tournament, but it has no rating. Btw, it is flawed as many old puzzles. Need an engine to figure that out!

The OP gave the position incorrectly (missing BPs). But to complicate things, this study was unsound when originally published, before it was apparently fixed.
The ARVES site gives two versions of this study on the composer's page. https://www.arves.org/arves/index.php/en/halloffame/693-belyavsky-albert-1934-2018
It looks like the original was the one without the BPa7 (it has a BPc6 missing in the OP diagram), because after 1.Rh8+ Ke7 2.Nxc6+ Kf6, 3.Rxd8 also works besides the intention 3.Rg8. But with the a7-P added, the study seems to be fixed, since Stockfish evaluates the alternative 3.Rxd8 at about +2.4 – hopefully not good enough to win...
BTW this study is often quoted without the first three moves, as in the Daily Puzzle from a couple of months ago. https://www.chess.com/daily-chess-puzzle/2022-10-30 That's of course unfortunate, since the brilliant 3.Rg8! is gone. The resulting position is a forced M9 that SF solves instantly, as it becomes a checking fest. This truncated version is quite popular with players though, and that Daily Puzzle has almost 1800 comments, which could be a record.

Good research! Thank you, Rocky.
Wow it's so easy that anybody could do it
That's not windmill. Let's understand the terms Windmill. The series of discover checks which lead to winning more material is called windmill.
I saw it before and it is a very beautiful combination! However it is not #12 as announced. Also it is unsure that it is a correct endgame study win since white has different ways to get a great (winning?) advantage.
