Microsoft delivers its ‘other’ tablet operating system: Windows Embedded Compact 7
Microsoft announced general availability on March 1 of the final version of its Windows Embedded Compact 7 operating system, codenamed “Chelan.” — Microsoft posted a 180-day trial version …
Context & Ripple Effects
This release closes a chapter that began when Microsoft abandoned the in-progress Windows Mobile 7 rewrite — the project whose collapse was dissected in an account of what derailed that train — and pivoted instead to the clean break that became Windows Phone 7, which began shipping last October to largely positive reviews. With phones now on their own codebase, the company has been left running parallel operating system tracks for everything else.
General availability of Windows Embedded Compact 7, codenamed Chelan, formalizes one of those tracks: a compact, componentized OS aimed at slates and specialized devices rather than the desktop Windows experience. Coverage syndicated the same day framed it against Microsoft's tablet ambitions, including reported Windows 8 design demos planned for June — meaning Microsoft enters 2011 pitching more than one 'tablet' answer to OEMs at once.
First-order effects
- OEMs building ARM-based tablets and dedicated devices gain a shipping, licensable Microsoft OS today, distinct from desktop Windows 7, which remains too heavy for that hardware class.
- Microsoft now fields two competing answers to the tablet question simultaneously — Embedded Compact 7 and desktop Windows — leaving its own slate partners to choose between them.
Second-order effects
- Chipmakers and board vendors in the embedded ecosystem get a renewed Microsoft option alongside Linux-based alternatives, sharpening competition for design wins in non-phone devices.
- The split raises the cost of Microsoft's messaging: every Embedded Compact 7 tablet pitch must be reconciled with the desktop-Windows slate story the same sales teams are telling.
Third-order effects
- If the pattern holds, Microsoft's OS portfolio consolidates into form-factor-specific branches rather than one Windows everywhere — a structure that determines which codebases inherit future features like the natural-user-interface work Kinect's success has energized internally.
- Sustained dual-track tablet strategies invite OEM and developer confusion over where Microsoft's platform investment actually lands, a fragmentation risk regulators and competitors alike will watch.
The trend: Microsoft is splitting its operating system strategy by device class — phone, embedded/slate, and PC — rather than converging on a single Windows.
