Microsoft is retiring the standalone "Windows 10 S" SKU and folding its restrictive, store‑only model into a configurable S Mode that can be enabled on Windows 10 Home, Pro, Enterprise and Education — a shift that simplifies Microsoft's SKU strategy but also raises questions about upgrades, pricing reports, and the long‑term role of a locked‑down Windows experience.
Windows 10 S debuted in 2017 as a lightweight, secure configuration aimed primarily at education and low‑end devices. The core idea: run only Microsoft‑verified apps from the Microsoft Store and lock the platform down for better performance, battery life and manageability. The Surface Laptop was the high‑profile showcase for the new SKU, which many observers compared to Chrome OS in purpose if not execution.
Microsoft's early rollout included a promotional window allowing many customers to leave Windows 10 S for a full Windows edition (notably Pro) at little or no charge during an initial grace period. That promotion was later extended; after the free period ended, multiple outlets reported a switch fee of roughly $49 for upgrading from S to Pro. Those pricing signals and the SKU complexity soon prompted Microsoft to rethink the strategy.
By early 2018 Microsoft executives confirmed the company would stop treating Windows 10 S as a separate SKU and instead make the same lock‑down functionality available as an S Mode toggle for existing Windows SKUs. That change was intended to reduce confusion among consumers and OEMs, and to make S Mode a configurable option rather than another license SKU.
That guidance corrected earlier marketplace confusion: while some reporting and OEM guidance described a $49 upgrade cost to move from S to Pro after the promotional window closed, Microsoft’s formal messaging later emphasized the no‑charge policy for switching out of S Mode on current devices. Observers and tech press documented both the earlier fee reports and the later clarification, so readers should treat historical price claims with caution and consult Microsoft’s support pages or their OEM for device‑specific policies.
At the same time, some reports and syndicated articles contained conflicting claims about pricing or upgrade terms — for example, summaries that asserted a $49 fee applied across the board for moving to Pro or Enterprise while saying Home upgrades would remain free. Those pricing summaries did not match Microsoft’s later, clearer guidance that switching out of S Mode carries no charge; they appear to reflect either outdated promotional rules or OEM‑specific practices that existed during the initial marketing window. Readers should treat any single price figure from secondary articles as provisional and check the Microsoft Store or OEM documentation for device‑specific details.
S Mode represents a pragmatic middle ground: it retains Windows’ flexibility for enterprises and power users while giving schools and nontechnical consumers a locked, maintainable environment when they want it. The transition from a separate product to a configurable mode reduces SKU complexity, but the one‑way exit, compatibility tradeoffs and past messaging inconsistencies mean careful planning and clear communication are still essential for organizations and consumers considering S Mode devices.

What Microsoft announced and what it means
S Mode vs. Windows 10 S (terminology and model)
- Windows 10 S (the original SKU) — a distinct product shipped on select devices in 2017.
- Windows 10 in S Mode — a configuration or mode that can be enabled on mainstream SKUs (Home, Pro, Enterprise, Education), offering the same Microsoft‑Store‑only app policy and a restricted execution environment.
- OEMs can ship familiar SKUs (Home/Pro/Enterprise) with S Mode enabled, reducing SKU proliferation and simplifying licensing choices.
- Administrators and end users can think about S Mode as a device policy rather than as a permanent product purchase, which opens clearer paths for both pre‑deployment and classroom-managed devices.
Can users leave S Mode? Is it free?
Microsoft’s published guidance and subsequent executive commentary clarified that switching out of S Mode is free, and the action is one‑way — once a device leaves S Mode it cannot return to the confined experience. Official Microsoft support documents outline the process (Settings → Update & Security → Activation → link to the Microsoft Store "Switch out of S mode" page), and confirm there is no charge to make the switch.That guidance corrected earlier marketplace confusion: while some reporting and OEM guidance described a $49 upgrade cost to move from S to Pro after the promotional window closed, Microsoft’s formal messaging later emphasized the no‑charge policy for switching out of S Mode on current devices. Observers and tech press documented both the earlier fee reports and the later clarification, so readers should treat historical price claims with caution and consult Microsoft’s support pages or their OEM for device‑specific policies.
The user‑behavior signal Microsoft used to redesign the SKU
Internal metrics shared with the press indicated a nuanced adoption pattern that likely drove the S Mode decision:- On third‑party, low‑end devices Microsoft reported roughly 60% of users remained in S Mode (i.e., did not switch out).
- Of the users who did switch away, about 60% did so within 24 hours of first using the device.
- If users did not switch within the first week, about 83% remained in S Mode beyond that window.
Verifying facts: what the record shows (and where reporting diverged)
Multiple reputable outlets and Microsoft’s own support documentation corroborate the central policy shift to S Mode as a configuration across SKUs. The Verge, The Washington Post, Tom’s Hardware and Business Insider all summarized Joe Belfiore’s public comments and Microsoft blog posts announcing the change. Microsoft’s official support pages describe how S Mode behaves, how to exit it, and the irreversibility of that action.At the same time, some reports and syndicated articles contained conflicting claims about pricing or upgrade terms — for example, summaries that asserted a $49 fee applied across the board for moving to Pro or Enterprise while saying Home upgrades would remain free. Those pricing summaries did not match Microsoft’s later, clearer guidance that switching out of S Mode carries no charge; they appear to reflect either outdated promotional rules or OEM‑specific practices that existed during the initial marketing window. Readers should treat any single price figure from secondary articles as provisional and check the Microsoft Store or OEM documentation for device‑specific details.
Technical and operational details
How S Mode works (short technical summary)
- App installation: Only apps published in the Microsoft Store are installable while a device is in S Mode. Traditional Win32 installers and unsigned desktop apps cannot be run.
- Default browser and search: S Mode historically favored Microsoft Edge as the default browser and Bing as the default search, but policy enforcement centers on app origin rather than the browser alone.
- Security model: The restriction to Store apps reduces attack surface, since Microsoft vets Store packages and the Store uses packaging and sandboxing constructs that limit privilege escalation compared with arbitrary Win32 installers.
- Irreversible exit: When a user chooses to exit S Mode, the system makes the change permanent; there is no supported rollback to S Mode without reimaging the device.
Managing S Mode in an enterprise or education deployment
- Pre‑deployment: IT teams can provision devices with S Mode enabled to simplify security baselines for student or kiosk devices.
- Exceptions and AV/security tooling: Microsoft indicated S Mode will allow for certain trusted security agents or management tools in enterprise configurations; implementation details depend on the particular enterprise management stack and the version of Windows being deployed. The commercial story differs somewhat from consumer devices, so enterprise teams should test management tools end‑to‑end in S Mode before mass rollouts.
Benefits: why S Mode made sense
- Improved security and manageability: By restricting app sources to the Microsoft Store and using modern app packaging policies, S Mode significantly reduces vectors for malware and drive‑by installers.
- Performance and battery life: On low‑end devices with limited CPU and storage, the simplified environment helps sustain snappier startup times and steadier batteries.
- Simpler choices for education buyers: Schools that want a locked, easy‑to‑administer experience can ship devices that behave like Chromebooks while retaining Windows ecosystem compatibility where available.
- Lower training overhead: For nontechnical users, the Store‑only model reduces the need for guidance around app downloads, installers and credential handling.
Risks and tradeoffs: what to watch
- App compatibility and ecosystem limits: Many mainstream desktop applications — including legacy enterprise tools, niche professional creative software, and many popular games — are not available via the Microsoft Store. Users who depend on such apps will need to exit S Mode. This creates friction for BYOD scenarios and power users.
- Peripheral and driver support: S Mode devices can still face driver or peripheral compatibility constraints, particularly for specialist hardware where vendor drivers were historically distributed as Win32 installers.
- Confusion over pricing and policies: As the early rollout showed, mixed messages about upgrade fees and SKU names created confusion for buyers and channel partners. Microsoft’s later clarifications solved some of this, but fragments of the older narrative still persist in some articles and OEM materials.
- Irreversible exit: The one‑way nature of leaving S Mode is a technical and policy risk — especially for school or shared devices where a user might permanently remove the protective mode and expose the device to unmanaged software thereafter. Admin workflows must consider controlled accounts and imaging processes to mitigate misuse.
- End‑of‑life and platform transitions: Windows 10 itself reached end‑of‑mainstream updates scheduling and faces end‑of‑support considerations (for example, Microsoft has previously announced Windows 10 support timelines). Devices still on Windows 10 S / S Mode will need migration plans aligned with Microsoft’s general lifecycle guidance.
Practical guidance — for consumers, schools and IT admins
If you run a device in S Mode
- Check whether the apps you need are available in the Microsoft Store before committing to a long‑term S Mode deployment.
- If you have to install legacy Win32 apps (e.g., specialist printing software, industry tools), plan to exit S Mode during imaging or provisioning, and secure the device with a managed AV and policy baseline afterwards.
How to switch out of S Mode (consumer steps)
- Open Settings (Windows key + I).
- Go to Update & Security → Activation.
- Under the "Switch to Windows 10 Home" or "Switch to Windows 10 Pro" section click "Go to the Store".
- On the Store page, select the Get button for the “Switch out of S mode” (or similar) entry. The system will apply the change and allow installations from outside the Store. This process is free and irreversible.
For school and enterprise IT
- Use imaging and device management to ensure that S Mode is configured consistently, and establish a documented pathway for reverting or reimaging devices if a supervised rollback to S Mode is necessary.
- Build white‑listing processes for critical Win32 apps that must run on devices that will be taken out of S Mode.
- Communicate clearly with procurement teams about SKU choices: shipping a device with S Mode enabled on Home vs. Pro vs. Enterprise has different upgrade and feature implications.
Why Microsoft’s pivot matters for Windows strategy
Converting Windows 10 S from a separate SKU into a universal S Mode configuration reflects several strategic priorities:- SKU rationalization: Reducing SKU confusion and allowing OEMs to ship mainstream SKUs with a preconfigured mode simplifies channel messaging and reduces licensing permutations.
- Competing with Chrome OS: Microsoft’s approach acknowledges the demand for locked‑down, easily managed devices in education while trying to preserve Windows’ larger app and enterprise ecosystem.
- User segmentation by behavior: Microsoft’s internal adoption metrics — users who switch immediately, and those who never do — explain why a mode makes more sense than yet another SKU: it lets devices target specific user needs without forcing a permanent product identity.
Critical analysis: strengths, unanswered questions and long‑term risks
Notable strengths
- The S Mode approach aligns product packaging with user behavior: most non‑power users gain real value from a locked environment; making it a mode reduces friction for OEMs and enterprise purchasers.
- Free, one‑click switching (via the Store) is simple and reduces buyer fear about being trapped, which should improve adoption of S Mode on devices intended for managed contexts.
Potential risks and open questions
- Policy clarity and communication: Messaging around upgrades and fees in early rollouts was inconsistent. Any future changes to Store policies, enterprise licensing or upgrade fees would need to be communicated clearly to avoid repeating that confusion.
- Enterprise feature parity: The idea that certain security or AV products would be supported in S Mode raises architectural questions: if traditional AV is allowed, does that undermine the simplification premise? Enterprise customers require clear guarantees about management tool behavior and support contracts.
- Platform fragmentation: If OEMs or retailers continue to advertise "Windows 10 S" as a product name in their marketing materials, customer confusion will remain. Microsoft must ensure consistent labeling in retail channels and OEM firmware to prevent mismatch between marketing claims and actual device behavior.
- Long‑tail app support: Many vertical industries rely on legacy Win32 applications. S Mode’s very nature makes it unsuitable for those contexts unless disciplined exception management and imaging strategies are used.
Takeaways
- Microsoft’s shift from a distinct Windows 10 S SKU to an integrated S Mode model simplified the company’s product lineup and matched how users actually behaved: power users exited early, while most of the intended audience remained in the secured mode.
- Public reporting initially mixed messages on upgrade pricing and business rules; Microsoft later clarified that switching out of S Mode is free and that the change is irreversible, so buyers should verify device specifics at purchase time.
- For IT teams and schools, S Mode offers a workable path for Chromebook‑style device management within the Windows ecosystem — but only with careful planning around app availability, imaging, and management tooling.
- Any historical claims about a fixed $49 upgrade fee or oddly specific upgrade price splits between Home/Pro/Enterprise should be treated as provisional unless confirmed by official Microsoft documentation or the device OEM; the record shows both early promotional fees and later policy clarifications.
S Mode represents a pragmatic middle ground: it retains Windows’ flexibility for enterprises and power users while giving schools and nontechnical consumers a locked, maintainable environment when they want it. The transition from a separate product to a configurable mode reduces SKU complexity, but the one‑way exit, compatibility tradeoffs and past messaging inconsistencies mean careful planning and clear communication are still essential for organizations and consumers considering S Mode devices.
