The recount in Wisconsin, and the coming ones in Michigan and Pennsylvania will not change the outcomes in any of the states.
No recount ever changes thousands of votes. I do not think that is the purpose.
The recounts, if done by hand, which can be demanded, may take longer than the last day for completing the official counts in a state and directing Electoral College voters. If all 3 states miss the deadline, Trump is at 260, Hillary at 232. No one hits 270.
