Middle earth after the war was won

Lets imagine the mille earth after the war with Sauron had been won. What happened to the Orcs? The humans on Saurons side apparently retreated bac to Easterland but the only mention of the Orcs after Saurons defeated was that the went into the deepest holes they could find.



Did the Dwarfs regain their original grandeur? I mean their ancestral home was occupied by Orcs so did they kick them out? Did Balrogs and Trolls disappear?
