Microsoft splits Windows & Devices Group; Rajesh Jha to lead Experiences & Devices, Scott Guthrie to lead Cloud + AI Platform, Harry Shum to lead AI + Research
Context & Ripple Effects
This 2018 reorg is Satya Nadella breaking up Terry Myerson-era Windows & Devices into three reporting lines — Rajesh Jha's Experiences & Devices, Scott Guthrie's Cloud + AI Platform, and Harry Shum's AI + Research — formally separating the client business from the cloud platform it was previously bundled with. The AI + Research piece extends what Microsoft had already built when it consolidated Bing and Cortana into a combined AI and Research group in 2016.
The split's afterlife is the real story: two years later Microsoft reversed course on the client side, [[a:950279|re-merging Windows software and hardware into a single Devices + Windows group under Panos Panay]]. And the Experiences & Devices organization Jha got in this reorg defined his remit until his retirement announcement in 2026, after which LinkedIn chief Ryan Roslansky took over a new Work Experiences Group spanning Teams.
First-order effects
- Scott Guthrie's Cloud + AI Platform absorbs the server and cloud platform businesses, making Azure's engineering leadership co-equal with — no longer subordinate to — the Windows organization.
- Rajesh Jha takes Windows, Office, and devices into one Experiences & Devices unit, while Harry Shum's AI + Research consolidates the company's AI and research assets outside both.
Second-order effects
- Splitting Windows from the cloud platform sets up the 2020 correction, when Microsoft folds Windows software and hardware back together under Panos Panay — evidence the three-way split strained device-software coordination.
- Jha's eight-year run atop Experiences & Devices ends with the group redrawn again as Ryan Roslansky's Work Experiences Group, pulling Teams and other work products under LinkedIn's former CEO.
Third-order effects
- If the pattern holds, Microsoft's org chart keeps oscillating between bundling and splitting the client stack against cloud and AI — each reshuffle reassigning the same assets rather than shrinking them.
- The recurring elevation of cloud-and-AI leaders (Guthrie in 2018, the AI-centric groupings since) points to organizational structure tracking where Microsoft sees its center of gravity moving.
The trend: Microsoft has spent nearly a decade redrawing its org chart along an experiences-versus-cloud-AI axis, with each reorg reassigning Windows, devices, and AI assets to match shifting strategic weight.
