Micsosoft has recently given good reasons to not automatically update Windows. Back in October, they put out their monthly update that killed thousands if not millions of Win 10 installations. Then, in response to the bad update, they issued a new one a couple of days later and it wiped out many more computers. Two really bad updates in one month are reason enough to wait and see if the update even has a decent chance of working. Remember the old saying, "If it isn't broke, don't fix it." All too often, the updates will break something that was working.
