Check out Richard Harris's Fatherland. It's a murder mystery that takes place in Berlin in 1964 after Germany won WWII. They were preparing for Hitler's 75th b-day, there were no Jews left at all and all Slavs were slave laborers in what used to be Russia. All cars were black or brown. Joseph Kennedy was president of the US and the Cold War was between the US and Nazi Germany.

I'm not sure how Hitler could have won unless he would have finally handed the real decision making over to his generals. By the time von Stauffenburg launched his assassination attempt, I dare say, killing Hitler would have been a blow to the Allies. Hitler was his own worst enemy, overextending supply lines, firing competent generals, micromanaging everything. Had he let the pros run things, Germany could very well have won even with the US entering.

But... if there were no US boots on the ground or even bombing campaigns, the Russians obviously would not have stopped at the Elbe. They'd have gone all the way to France maybe farther. That would have made for a very different Cold War.
