Finally we look at captains with the most wins, most losses and most draws.
Most wins (14 and more):

Here, and in the rest of the post, we will see that the toppers will generally be those who captained in the most Tests. GC Smith with 53 wins had captained in the most Tests (108). RT Ponting is next with 47 wins.
Among current players, V Kohli has the most wins (33). That is also the most by an Indian captain.
Most losses (12 and more):

Unsurprisingly, it is also headed by GC Smith with 28 losses. Next is SP Fleming with 27.
Among current captains, JO Holder has the most losses (19). For India, MAK Pataudi leads with 19.
Most draws (12 and more):

For a change, this is headed by another captain AR Border with 39 draws (including 1 tie). Next is SM Gavaskar with 30. He was well known for his defensive captaincy. Like Border, he had a weak Test team most of the time. GC Smith is third with 27.
Among recent captains, AN Cook leads with 13 draws.
