White wins as Black King can't get to the end in time, last move scuppered by the other advanced pawn leaving him unable to avoid being in check.Actually no...if black goes diagonal and takes the advanced pawn on route, he cuts off the other pawn too and white is stuffed.
Am i right ?
Or am i right
Or am i right, right, right.......
Changed my mind....black wins !

If so, prove it.
White plays 1. h4 and Black resigns.
(2. h5, 3. h6, 4. h7, 5. h8Q 1-0 against any Black defense except the pointless advance of the a-pawn, which delays White's pawn promotion until the sixth move from the diagram: 1. h4 a5 2. h5 a4 3. h6 a3 4. h7 a2+ 5. Kxa2 1-0)

But back to the chess puzzle, I see the draw attempt now:
1. h4 Kc7 2. h5 Kb6 3. h6 Ka5 4. h7 b6 5. h8=Q a6 1/2-1/2

1.h4 (the only move white can make without losing)
If black gets his king to a5 and then his a and b pawns to a6 and b6, he stalemates regardless of what white does. And black can do this, except...
I pushed the white h-pawn to h8 and underpromoted to a knight. I still can't find a win for white though. Black leaves the b-pawn on b7 just in case white underpromotes. Black doesn't play b6 and stalemate unless white promotes to anything OTHER than a knight. Uuugh.
Once I underpromoted to a knight I still couldn't find the answer. Black's king comes back to pester my knight and f-pawn after I capture the black f-pawn. If I bring the white king across the board to help then black's pawns start rolling down the board. Double uuugh!
I give up. Is it a forced draw?

But the draw attempt fails to under-promotion:
5. h8=N a6 6. Ng6! fxg6 7. f7 etc. 1-0
This puzzle rocks. I'm going to investigate further before I commit to this solution, but as of now I answer that White wins.

I still can't get a white win. But underpromting is the only option so far that's playable.

1. h4 Kc7 2. h5 Kb6 3. h6 a6 4. h7 Ka5 5. h8=N Kb6 6. Nxf7 Kc7 7. Ne5 Kd8 8. f7 Ke7 9. Kb2 a5 10. Kb1 a4 11. Kb2 a3+ 12. Ka2 b6 13. Ka1 Kf8 and I think White can drop the f-pawn with 14. Nd7+ and come out on top.
This will take a little while to verify...
