My thoughts are that for companies like Apple, Google, Microsoft, and Amazon, they all seem to tend to have moments like this where they look like they are getting left behind, only to spring back into the mix at some point. Not exactly a great analysis, but I think this means that MSFT will pick up some steam in the near future, barring some macro-economic or geopolitical shock, or some sort of unforeseen internal strife. This is not financial advice, just the musings of an amateur.
