Leaving Windows 10: The Real Deadlines, and Your Options When Your PC Can't Run Windows 11

On October 14, it will be one year since Windows 10 officially reached its end of support. Expect a wave of countdown articles, and expect most of them to be built on a date that is no longer true. The deadline the internet spent 2026 repeating, October 13, 2026, quietly ceased to exist in June, when Microsoft edited its support pages and gave consumer PCs another year of security updates. Hardly anyone noticed, because there was no announcement, just a documentation change.

We noticed late, too. Our September fact-check of the "Linux is exploding in Europe" claims cited the October 2026 cutoff; we have since corrected it, and this article is built on what Microsoft's own pages say as of October 1, 2026. The extra year changes the question. It is no longer "what do I do in two weeks", it is "where do I want this computer to be in twelve months". For the hundreds of millions of PCs that cannot run Windows 11, that question has a better answer than most people think, and much of it is open source.

When Does Windows 10 Actually Stop Getting Security Updates?

Three dates matter, and they are different things.

October 14, 2025 was the official end of support: no more feature updates, no more fixes, no technical assistance, per Microsoft. From that day, a Windows 10 PC receives security patches only if it is enrolled in the Extended Security Updates (ESU) program.

October 13, 2026 was the original end of the consumer ESU year, the date our earlier article and most 2026 coverage cited. It no longer applies to consumers. Around June 25, 2026, Microsoft updated its documentation to extend the program, a change first spotted by Windows Latest and confirmed to press, with Microsoft saying the extension "provides customers with more time to transition to a new Windows 11 PC", as Help Net Security reported. Business ESU pricing is a separate, paid, per-year track.

October 12, 2027 is the real consumer deadline now. Microsoft's end-of-support page states that enrolled devices "will continue to receive critical and important security updates through October 12, 2027". Note what ESU is not: no new features, no non-security bug fixes, no support line. It is a patch drip, designed to keep you safe while you leave.

That is the whole correction in one line: the cliff everyone planned around moved a year, and the planning time it bought is only worth something if you use it.

Can Your PC Upgrade to Windows 11 at All?

If your machine qualifies, the upgrade is free and this article is short. The bar, per Microsoft's requirements: a TPM 2.0 security chip, Secure Boot, and a processor on the approved list, which in practice means Intel 8th generation or AMD Ryzen 2000 and newer, chips from around 2018. The PC Health Check app gives a yes or no.

The problem is the size of the no. Analyst firm Canalys estimated that about 240 million PCs cannot meet Windows 11's requirements, machines that work fine and are refused anyway, and put the potential e-waste at 480 million kilograms. These are not museum pieces: a 2017 laptop with an SSD handles mail, browsing, documents and video calls without complaint. The hardware gate is why "just upgrade" is not an answer for roughly one PC in five that was running Windows 10.

Yes, registry workarounds exist that force Windows 11 onto unsupported hardware. Microsoft's own guidance says such PCs are not entitled to receive updates, and update eligibility on these installs has tightened over time. An operating system whose patches can stop arriving at any moment solves nothing; you would be trading one unsupported system for another with extra steps.

How Do You Claim the Free Extra Year of Updates?

Enrollment lives in Settings, under Windows Update, on any Windows 10 PC running version 22H2. Three routes, per Microsoft: free if you sync your PC settings through a Microsoft account, 1,000 Microsoft Rewards points, or a one-time $30 purchase. One consumer license covers up to 10 devices, and you can enroll at any point until the program ends on October 12, 2027; already-enrolled PCs were extended automatically.

Readers in the European Economic Area get the lighter version: after consumer organizations led by Euroconsumers challenged the strings attached, Microsoft dropped the settings-sync condition for EEA consumers, though a Microsoft account and a periodic sign-in are still required, and Microsoft notes enrollment options vary by region.

Enroll even if you plan to switch next month. It costs nothing, and it keeps the machine defended while you decide. Just do not mistake the runway for a destination: in October 2027 this question returns, and the hardware will be a year older. One asterisk for gamers: Nvidia ships its last Game Ready driver for Windows 10 in October 2026 and moves to quarterly security-only driver fixes after that, which makes the extension far less generous for a gaming PC.

Is Linux a Realistic Replacement for a Windows 10 PC?

For the machines Windows 11 rejects, it is the most durable answer on the table, and the one with no invoice attached.

Start with what the move actually costs in hardware terms: nothing. The same 2015 laptop that fails Microsoft's TPM check runs Linux Mint comfortably; Mint's stated minimum is 2 GB of RAM against Windows 11's gate of a 2018-era CPU. There is no activation, no license, and the updates do not end on a vendor's schedule you cannot see: Linux Mint 22.x is supported until 2029, Ubuntu 24.04 LTS runs to 2029 with free security coverage, extendable to 2034 with Ubuntu Pro, which is free for personal use on up to five machines, and the next long-term release after that will be free too.

We looked hard at the adoption numbers a few days ago, in our Linux adoption fact-check, and the honest picture is useful here. The viral "Linux hit 9 percent" posts were largely bot traffic; the real worldwide share is 4 to 5 percent and climbing slowly. But inside that sober number, the movement is real: Germany doubled to about 6.5 percent in under three years, and Zorin OS, a distribution built to feel familiar to Windows users, logged 2 million downloads in under three months, more than three-quarters from Windows machines. Switching in 2026 means joining a measured migration, not a leap of faith, and not a stampede either.

Which one? For a Windows 10 refugee the shortlist is short. Linux Mint looks and behaves the way Windows users expect: taskbar, menu, system tray, no surprises. Zorin OS goes further and offers a Windows-like layout as a setting. Ubuntu is the mainstream pick with the biggest community and the most answers one search away. All three install from a USB stick, and all three let you run the full system from that stick first, so you can test your Wi-Fi, your printer and your nerve before touching the disk.

The software question deserves honesty in both directions. Chrome and Firefox are identical. LibreOffice opens your documents, and Microsoft 365 works in the browser. Gaming stopped being the punchline: Valve's Proton layer runs a large share of the Steam catalog, and the Steam Hardware Survey put Linux at 3.90 percent of gaming machines in August 2026, close to its highest levels ever. What does not work: the full Adobe suite, some professional tax and CAD packages, and a handful of anti-cheat multiplayer titles. If one of those is your livelihood or your evening, verify it first; everyone else is better served than they expect.

You do not have to do it alone, either. The End of 10 campaign, backed by KDE and other open-source communities, lists repair cafes and local groups that help people install Linux on exactly these machines, for free. Their environmental argument is worth repeating: over 75 percent of a computer's carbon footprint comes from manufacturing, so the greenest computer is almost always the one you already own.

What About ChromeOS Flex, or Doing Nothing?

ChromeOS Flex is Google's free system for old PCs and Macs, built on a Linux foundation and certified on around 600 device models. For a machine that is 90 percent browser anyway, it is genuinely pleasant: boots in seconds, updates itself, shrugs off malware. Two caveats: it runs no Windows applications and no Android apps, and each certified model has its own support end date on Google's list, so check yours before committing. It is a fine answer for the kitchen laptop; it is not an answer for a working machine, and unlike a Linux distribution it trades one vendor's schedule for another's.

Doing nothing is the default, and the worst of the options. An unsupported operating system does not stop working; it stops being defended. Every patch Tuesday, attackers compare Microsoft's fixes against the systems that will never receive them, and the unpatched pool is enormous: StatCounter's September 2026 data still shows about a quarter of Europe's Windows desktops on Windows 10, roughly 28 percent worldwide. If you genuinely cannot deal with this today, at least take the free enrollment: it is the difference between unpatched and patched until October 2027, for the cost of a settings toggle.

Which Option Fits Which Machine?

Every exit has a clock. Here they are, side by side, as verified on October 1, 2026:

Read the table from the left: the question is not which system is best, it is which clock you are comfortable living on, and what this particular machine is for.

Will Your Privacy Setup Survive the Move?

One worry we can remove from your list entirely. The tools that protect your traffic were never Windows features: WireGuard and OpenVPN, the two protocols doing the real work in most VPN connections, are open-source projects that run on every system in this article, which is exactly why a VPN subscription is one of the few things you do not have to re-buy when you change operating systems.

On Linux, Le VPN works today through those standard open-source tools: OpenVPN, with our step-by-step Ubuntu setup guide, or WireGuard, by importing the configuration files from your client area into the WireGuard tools, on Mint and Zorin just as on Ubuntu. And we can finally say more than "it is in the works": our native Linux app is finishing its last rounds of testing with beta users, and release is close. We will not name a date until it ships, but if you move to Linux this autumn, the app is coming to meet you there.

The same logic covers every other road out of Windows 10. Pick a new Windows 11 machine, a Mac, or a reborn Linux laptop: there is a Le VPN app or setup path for each, and one subscription covers 10 simultaneous connections, so the old laptop you revive with Mint joins the same account as your phone, your desktop and your TV. Whatever you switch to, your VPN moves in with you, with a 30-day money-back guarantee if you are only now setting one up.

A year from the official end of Windows 10, the real deadline turns out to be October 12, 2027, and the real decision turns out to be bigger than a patch schedule: whether the next decade of your computing runs on terms a vendor sets, or on terms you can read. The machines Microsoft left behind have rarely had better options. Enroll for the free year today, put a Linux stick in your pocket this weekend, and make the choice while it is still calm.
