Windows gamers have quietly completed a generational shift: Valve’s September 2025 Steam Hardware & Software Survey shows Windows 11 (64‑bit) leading the platform for the first time, while Windows 10 continues a steep decline as Microsoft’s support deadline looms. The numbers are unmistakable — a broad migration toward Windows 11 among active Steam players, simultaneous with a new Windows 11 annual feature update (version 25H2) and mounting public pressure over Windows 10’s upcoming end of free security updates on October 14, 2025.
At the community level, forum and analysis threads archived on WindowsForum demonstrate the conversational and technical reaction among enthusiasts — validating how the Steam data was interpreted, debated and acted upon within the gaming community. Those community threads are consistent with the published survey numbers and the broader media coverage.

Background
What the Steam survey measures — and what it doesn’t
Valve’s Hardware & Software Survey collects voluntary, anonymous data from Steam clients about operating systems, GPUs, CPUs, memory, and display resolution. It is a high‑value snapshot of active PC gamers on Steam, but it is not a census of all desktop users; Steam’s audience skews toward newer, upgradeable hardware and gaming‑focused machines. That makes the survey an excellent barometer of the gaming market specifically, but it should not be read as a substitute for wider market trackers.The immediate catalyst: Windows 10 support end
Microsoft has confirmed that Windows 10 Home, Pro, Enterprise and Education editions will reach end of support on October 14, 2025 — after that date feature updates, non‑security fixes and routine technical support end, and free security patches stop. Microsoft is offering a consumer Extended Security Updates (ESU) option and specific enrollment paths, but the mainline message from Redmond is: move to Windows 11 if your hardware supports it. The support calendar is the most concrete external deadline shaping consumer choices in the months leading up to October 14.The numbers: September 2025 snapshot
Windows 11 overtakes Windows 10 on Steam
- Windows 11 (64‑bit): 63.04% of Steam users in the September 2025 survey — a jump of roughly 2.65 percentage points month‑over‑month.
- Windows 10 (64‑bit): 32.18% — a drop of approximately 2.90 percentage points in the same period.
Platform share, and the remainder
- Windows overall still represents the overwhelming majority of Steam users at ~95.4%, with Linux and macOS together accounting for the small remainder. The survey reiterates that gaming remains a Windows‑centric market, even as niche increases for Linux (notably SteamOS/Arch variants) and macOS are visible.
Hardware highlights from the same survey
Valve’s data also tracks hardware trends that help explain the OS shift:- The mobile (laptop) NVIDIA GeForce RTX 4060 family remains among the most common GPUs in the Steam sample, reflecting the continued dominance of NVIDIA in the gaming GPU segment. Steam’s GPU table shows the RTX 4060 Laptop GPU, the desktop RTX 3060, and the RTX 3050 as notable entries in the top ranks. NVIDIA held roughly ~74% share of discrete GPUs on Steam in the most recent snapshot, with AMD around ~18% and Intel at ~7.7%. System memory commonly sits at 16 GB, six‑core CPUs remain widespread, and 1080p is still the primary display resolution for the majority of gamers.
Why the jump to Windows 11 accelerated in September
1) The calendar effect: EOL is a deadline, not a suggestion
End of support is a firm external deadline that triggers real‑world action. Gamers who had delayed or resisted upgrading to Windows 11 now face a clear security tradeoff: remain on an unsupported OS and risk exposure to unpatched vulnerabilities, or upgrade (or pay for ESU) to remain protected. The survey’s September uptick is tightly correlated with that calendar pressure.2) Windows 11’s 2025 update (25H2) and feature maturity
Microsoft rolled Windows 11 version 25H2 into general availability in late September 2025. That annual enablement package packaged steady refinements to the Settings app, accessibility features, and security tooling rather than major user‑visible novelties — but the release also serves a marketing and lifecycle function: it “resets” the support clock for Windows 11 devices and signals continued investment in the platform. For many users, the perception of an actively maintained, improving OS reduces upgrade friction.3) Gaming features and perceived value
Windows 11’s gaming‑facing features — DirectStorage, Auto HDR, tighter DirectX 12/12 Ultimate alignment and overall scheduler enhancements — have steadily accumulated value for gamers. While most titles still run on Windows 10, developers increasingly certify and optimize around the latest platform, nudging enthusiast users (a core Steam demographic) to upgrade earlier. The net effect is pragmatic: games and hardware vendors coalesce around the newer platform, and gamers with upgradeable rigs follow.4) Valve and ecosystem signals
Valve’s own moves — including announced plans to end support for Windows 10 32‑bit client variants in early 2026 — further signal the industry’s forward march. Steam’s commercial ecosystem is optimized for modern drivers and 64‑bit stacks; remaining on legacy bitness and older OS versions becomes increasingly inconvenient.Cross‑checking and context: independent verification
The Steam site is the primary data source and the definitive record for the survey. Independent trade outlets and reporting show the same trend: outlets focused on gaming and PC hardware (PC Gamer, Tom’s Hardware, Wccftech, PCGamesN and others) captured the same September surge and echoed Valve’s OS and GPU tables. Microsoft’s own lifecycle documentation confirms the October 14, 2025 end‑of‑support date and details on the consumer Extended Security Updates (ESU) program. Taken together, Steam’s raw numbers plus corroborating industry coverage and Microsoft’s lifecycle pages form a consistent, verifiable picture of migration.At the community level, forum and analysis threads archived on WindowsForum demonstrate the conversational and technical reaction among enthusiasts — validating how the Steam data was interpreted, debated and acted upon within the gaming community.

What the shift means for gamers, developers and Microsoft
For gamers
- Security and compatibility tradeoffs: Gamers who upgrade preserve security updates and compatibility with future AAA titles; those who remain on Windows 10 will need ESU or will face growing compatibility and security friction. The ESU path exists, but it’s a short, paid stopgap intended primarily for enterprises and users who cannot immediately transition.
- Performance gains depend on hardware and titles: Windows 11’s advantages are incremental for many existing rigs; the most visible gains appear on newer CPUs, NVMe storage with DirectStorage‑ready titles, and systems that leverage recent graphics and driver stacks. Gamers with older hardware may not see immediate performance leaps, though security is the larger driver.
For game developers
- Targeting choices tighten: With a majority of active Steam players on Windows 11, studios can increasingly assume Windows 11 parity for testing and optimization, while still supporting Windows 10 for legacy reach. Smaller studios will still factor in Windows 10 users for a while, but the delta continues to shrink.
For Microsoft
- Policy and perception management: Microsoft benefits from migration when it increases the proportion of users on a single, supported platform, but the company faces reputational pressure from consumer groups and repair advocacy organizations urging longer support windows to avoid forced hardware replacements and e‑waste. Multiple petitions and industry letters from consumer advocacy groups (PIRG, Consumer Reports and European coalitions) have called for extended Windows 10 support or free ESU accommodations; some public petitions explicitly request support extensions to 2030. Those campaigns have received media attention and add political and PR complexity to Microsoft’s lifecycle choices. It is accurate to say organized groups and petitions pushed for an extension, though the specifics vary across countries and organizations.
Notable risks and caveats
Survey participation bias
The Steam dataset is optional and self‑selecting. Steam users are more likely to be gamers with upgradeable hardware, so the platform tends to show faster adoption of new OS and GPU generations than general‑purpose desktop trackers. Extrapolating Steam’s share to the global PC market without adjustment will overstate Windows 11’s penetration. Valve itself and independent press outlets repeatedly note this caveat.Conflicting snapshots and short‑term noise
Different outlets sometimes report slightly different percentage points for a given month because of how they interpret Valve’s tables (Windows‑only vs. total OS share) or minor timing differences when Steam republishes interactive tables. For example, some community summaries placed Windows 11’s share slightly higher or lower depending on whether they calculated relative to Windows‑only systems or all Steam users. The direction of change matters more than exact decimal points: the trend is unambiguously toward Windows 11. Readers should treat single‑point differences (±1–3 percentage points) as within expected reporting variance.Policy claims that need careful language
Some outlets described broad “coalitions demanding updates until 2030.” That headline is rooted in actual petitions and organized advocacy calling for much longer support windows or asking Microsoft to continue free security updates until around 2030, but there is no single global legal demand that obliges Microsoft to comply — rather, these are public advocacy actions. The specifics (which groups, which geographies, what precise timeline) vary, and readers should not conflate petition language with formal regulatory mandates. Where possible, refer to the original letters or petitions for precise claims.Practical guidance for Steam players and PC owners
- Check compatibility before upgrading:
- Run Microsoft’s PC Health Check or check "System > About" and Windows Update guidance to confirm whether your PC is eligible for Windows 11 25H2. If your device meets the requirements, upgrade is the simplest path away from ESU costs.
- Back up before you upgrade:
- Image your system drive or use Windows Backup / cloud storage. Hardware upgrades and OS enablement packages generally go smoothly, but a current backup protects game installs, save files and personalization settings.
- Consider ESU as a stopgap:
- If hardware prevents upgrading immediately, Microsoft’s consumer ESU program offers one year (with enrollment guidance differing by region) that covers critical and important security patches. ESU is a temporary protective choice, not a long‑term substitute for a supported OS.
- If you’re a developer or server admin:
- Use Steam’s and Microsoft’s published guidance when selecting minimum supported OS versions for new titles; allow a transition period to support Windows 10 users for a reasonable lifecycle window while prioritizing the majority platform (Windows 11) for future feature work.
- For gamers who want to avoid Windows 11:
- Evaluate alternate OS options (Linux distributions, SteamOS) only after confirming compatibility with your favorite titles and third‑party tools like anti‑cheat systems. Linux adoption on Steam is slowly growing but remains a minority share; compatibility varies by game.
Industry reaction and community perspective
Community threads collected by WindowsForum and other enthusiast sites show a mix of pragmatic acceptance, frustration, and activism. Many gamers welcome Windows 11’s incremental advantages and the security imperative behind the migration; others decry Microsoft’s hardware requirements and point to environmental and affordability arguments. Consumer advocacy groups and repair‑oriented NGOs have mobilized petitions and letters calling for longer support windows or more flexible ESU terms — a debate that reframes software lifecycle policy as an environmental and consumer‑rights issue, not just a technical one. The conversation will likely influence future regulatory attention on device lifecycles and right‑to‑repair style reforms.Bottom line
Valve’s September 2025 Steam Hardware & Software Survey shows a clear, verifiable migration of Steam users to Windows 11 (64‑bit), with Microsoft’s October 14, 2025 end‑of‑support date for Windows 10 acting as the central external catalyst. The data are consistent across Valve’s published tables and independent press reporting, and are reinforced by related developments — Microsoft’s 25H2 update, petitions and advocacy calling for longer Windows 10 support, and ecosystem signals such as Valve’s 32‑bit client deprecation. For gamers, the pragmatic tradeoffs are straightforward: upgrade to stay supported and compatible; enroll temporarily in ESU if you cannot; or plan for an alternative platform with careful testing. The migration trend is real, measurable and likely to accelerate as the EOL date passes.Quick checklist (for immediate action)
- Verify Windows 11 compatibility with PC Health Check.
- Back up games and profiles (Steam cloud helps, but local backups matter).
- Update GPU drivers and firmware before the OS upgrade.
- Consider ESU only as a stopgap; plan for hardware upgrades or OS alternatives if needed.
- Monitor Steam’s monthly survey for hardware and OS trends — it’s a practical gauge of the gaming ecosystem’s direction.
