Am I Running the Latest Windows Version? (How to Check)
Am I Running the Latest
Windows Version?
The latest supported Windows versions in June 2026 are Windows 11 24H2 and 25H2. Here is how to check yours, how to upgrade, what is new — and what Windows 10 end of life means for Kenyan users.
Windows 11 (June 2026)
coming late 2026
end of support
for eligible PCs
Running an outdated Windows version is not just missing features — it means missing security patches that protect your financial data, business files, and personal information from Kenya's increasingly active threat environment.
Windows versioning in 2026 is more confusing than it has ever been. Microsoft now releases features continuously throughout the year, so the version number matters less than whether your machine is actively receiving security updates. As Thurrott.com's 2026 Windows guide explains: "At the time of this writing, Windows 11 versions 24H2 and 25H2 are current and supported, and are functionally identical." This guide cuts through the confusion with a clear answer to every version question a Kenyan user needs answered.
Oct 2024
Windows 11 version 24H2 (OS Build 26100.x)
Still fully supported and receiving all feature updates. Home and Pro editions reach end of updates October 13, 2026 — Enterprise and Education editions remain supported until October 2027. Most refurbished laptops from Kenya's market come with Windows 11 24H2 pre-installed.
Oct 2025
Windows 11 version 25H2 (OS Build 26200.x) — THE LATEST
The current latest version of Windows as of June 2026. Microsoft confirms 24H2 and 25H2 are "functionally identical" — both receive the same feature and security updates. The latest cumulative update is KB5094126 (Build 26200.8655), released June 9, 2026. If you are on 25H2, you are fully up to date.
only 2026
Windows 11 version 26H1 (OS Build 28000.x) — NOT for existing PCs
Released only for new ARM devices (Qualcomm Snapdragon X2 laptops) launching in early 2026. Microsoft confirms: "26H1 is not designed as a feature update for existing devices." If you have an existing Intel or AMD PC, this version is not available to you — and you are not missing anything.
Late 2026
Windows 11 version 26H2 — Coming Soon
Microsoft has confirmed Windows 11 26H2 is the next annual feature update, currently in testing with Windows Insiders. Devices running 24H2 or 25H2 will upgrade via a small 174KB enablement package requiring just a restart. No new hardware requirements announced. Expected second half of 2026.
Oct 14, 2025
Windows 10 (All versions) — UNSUPPORTED
Windows 10 reached end of support on October 14, 2025. No more security updates, bug fixes, or technical support. Machines still running Windows 10 are increasingly vulnerable to malware, ransomware, and cyberattacks — particularly relevant given KE-CIRT's documented threat volumes in Kenya.
Version 24H2, Build 26100.x → You are current and supported. ✔
Version 23H2 or earlier → Your Windows 11 needs updating. ⚠
Windows 10 (any version) → End of support — upgrade needed. 🔴
If you are on Windows 11 but not on the latest version, upgrading is straightforward and free. Go to Settings → Windows Update → Check for updates. Windows will find and download any available version upgrades. The move from 24H2 to 25H2 is delivered as a standard update. For the upcoming 26H2, devices on 24H2 and 25H2 will receive it via a tiny 174KB enablement package — just a restart required, not a full reinstall.
If you are on Windows 10 and your PC supports Windows 11 — go to Settings → Windows Update and look for the Windows 11 upgrade offer. Microsoft has been pushing this automatically to eligible Windows 10 machines. If you do not see it, download the PC Health Check app from Microsoft's website to verify compatibility. Windows 11 is a free upgrade for all eligible Windows 10 machines.
What this means in Kenya specifically: KE-CIRT documented 3.37 billion cyber threats in Kenya in Q1 2026 alone. Running an unpatched operating system in this environment means your financial data, client files, M-Pesa credentials, and business records are increasingly exposed. The risk compounds every month that passes without updates.
What you should do: (1) Check if your PC can run Windows 11 — Settings → Windows Update, or download Microsoft's PC Health Check app. (2) If compatible, upgrade to Windows 11 for free immediately. (3) If not compatible — your PC does not meet Windows 11 hardware requirements (typically needs TPM 2.0 and 8th Gen Intel or newer) — consider upgrading the machine. All refurbished laptops we sell at Tech Convenience Store come with genuine Windows 11 activated, ready to use safely.
Windows 11 requires TPM 2.0 and a compatible processor — typically Intel 8th Generation or newer, AMD Ryzen 2000 or newer. If your machine does not meet these requirements, Windows Update will not offer the Windows 11 upgrade. You have three options. First, check whether your PC actually has TPM 2.0 — it may be present but disabled in BIOS. Search "TPM Management" in Windows search and press Enter — if it shows TPM 2.0, it may just need enabling in BIOS settings. Second, purchase an extended security updates (ESU) subscription from Microsoft — available for Windows 10 machines at a cost, giving you continued security patches for a limited time. Third — the most practical option for most Kenyan users — upgrade to a laptop that comes with Windows 11 pre-installed and meets all hardware requirements.
Every laptop we sell at Tech Convenience Store — HP EliteBook from 8th Gen, Dell Latitude from 8th Gen, Lenovo ThinkPad — meets Windows 11 requirements and comes with genuine Windows 11 activated. From KSh 26,500, you get a fully supported, actively updated operating system on an enterprise-quality machine.

Microsoft now delivers new features continuously throughout the year. What matters is not which exact version you are on — it is whether you are actively receiving security updates.
