Satya Nadella has only, but his impact has already been widely felt.
His comments during Microsoft's Q4 earnings call last week gave some of the clearest explanations yet of how he has sharpened the company's focus, giving it a more confident strategy for a more complicated world.
Alongside the by now well-practiced 'mobile-first, cloud-first' slogan, Windows remains the core for Microsoft under Nadella (hence its recent decision to), but it's a core that's being approached in a pragmatic fashion (hence the ).
On the earnings call, Nadella talked about the drive to reduce some of the, sparking misplaced excitement over what was thought to be a new OS move, but was really an initiative .
But that wasn't the only important internal rethink that's going on — his comments about Microsoft's approach to "dual-use" technology were interesting too.
"Everything we do starts with digital work and life experiences to delight dual-users – these are users who use technology both at work and in their personal lives. This is how we re-invent productivity," he said, noting that this means product teams for OneDrive and OneDrive for business, Outlook and Exchange and Skype and Lync are one team all focused on these dual-user scenarios.
He went on to clarify this a little later by saying: "When I think about productivity it doesn't separate out what I use as a tool for communication with my family and what I use to collaborate at work."
Now that might be the case for him, but it's not the case for most people. While the world of work remains for the most part solidly Microsoft, the consumer world is far more fragmented. When workers switch off their Windows PC they may well pick up an Android tablet or an iPhone instead.
Microsoft's challenge is persuading people to stick with Windows outside of the nine to five, because providing a better consumer offering is an important component of Microsoft's enterprise strategy in the long term.
Historically, that's something it's had mixed results with. Windows Phone is finding it hard to make progress in the mobile market, and is still a long way behind iOS and Android. Windows tablets have been underwhelming and it's still very early days for Microsoft's own Surface line.
Price is a big factor for consumers and Microsoft seems to understand that now — Nadella highlighted thatfor OEMs building a device under nine inches, and there's a cheap Windows licence for manufacturers who use Bing.
This, plus the lower hardware spec Microsoft requires of its manufacturers, means there could be a bumper crop of cheap Windows hardware by Christmas, he said: "This holiday season I think you'll see a lot of value notebooks. You'll see clamshells."
Whether these new devices can ignite consumer interest will be important. Nadella understands how the consumer and the business markets fit together for Microsoft. Much now depends on turning that strategy into reality.
