I think it's a bit of a pet peeve of mine when visiting this forum. There are a certain set of users that constantly recommend disabling Fast Start on Windows.
Why would you recommend that a user turn off Fast Start when it has nothing to do with the original question? Why would you recommend to someone they should decrease performance and increase start up time unnecessarily?
I have experienced zero issues because of Fast Start on Windows. It is possible that other users may actually be able to use it without issue too. So recommending it be turned off without a valid reason isn't the best idea.
