If you got a notification telling you Windows 10 support is ending and you’re not sure what to do next, you’re not alone — over 500 million devices are still running Windows 10. Here’s the honest answer: you probably don’t need to panic, and you almost certainly don’t need to run out and buy a new PC this week. But you do need a plan, because the clock is real. This guide walks you through exactly what to do if you want to upgrade Windows 10 to Windows 11 in 2026 — and what to do if your PC can’t make the jump.
First: What Actually Happened to Windows 10?
Microsoft ended mainstream support for Windows 10 on October 14, 2025. That means no more feature updates and no more free security patches — you’re now technically running an unsupported OS. However, Microsoft also offered Extended Security Updates (ESU) — a one-year paid extension that covers you until October 13, 2026. The cost is a one-time $30, or you can get a free ESU year via Microsoft Rewards points if you haven’t already.
What that means practically: if you’re reading this in early-to-mid 2026, you have some breathing room. You don’t have to upgrade right this minute. But October 2026 is when the window genuinely closes — after that, your Windows 10 machine gets no security updates at all, and running an unpatched OS on the internet is a real risk.
Is Your PC Compatible with Windows 11?
Before you do anything else, check if your PC can actually run Windows 11. Microsoft’s requirements are specific, and roughly 500 million existing PCs don’t meet them:
- TPM 2.0: Trusted Platform Module version 2.0 chip required
- Secure Boot: Must be enabled in BIOS
- 64-bit CPU with specific Intel/AMD generations (Intel 8th gen+ or AMD Zen 2+)
- 4GB RAM minimum (8GB recommended)
- 64GB storage minimum
The quickest way to check: download Microsoft’s free PC Health Check app from Microsoft’s website. It runs a compatibility scan in 30 seconds and tells you exactly which requirements your machine does or doesn’t meet. If the result is “This PC can run Windows 11,” you’re done — the upgrade is free and straightforward.
The most common failure reason is TPM. Many PCs from 2019–2021 actually have a TPM 2.0 chip, but it’s disabled by default in BIOS. Before assuming you need new hardware, check your BIOS settings for “TPM,” “fTPM,” or “PTT” — enabling it often resolves the compatibility issue without spending a dollar.
What Happens If You Stay on Windows 10 After October 2026?
Let’s be honest about the risk level, because most articles either dismiss it or exaggerate it.
Short-term risk (through mid-2027): Moderate. No new security patches means any newly discovered vulnerabilities in Windows won’t get fixed. Exploits tend to build up over months, not days. If you’re behind a router, running a reputable antivirus, not downloading sketchy files, and don’t have sensitive financial data on the machine — the near-term risk is manageable but real.
Long-term risk (2027 and beyond): High. The longer you go without security updates, the more exposure accumulates. The history of Windows XP and Windows 7 after their EOL dates is instructive — both saw significant malware spikes in the years following end of support.
If you use your PC for banking, taxes, business work, or anything with personal data: upgrade or replace sooner rather than later. If it’s a gaming PC or media box with no sensitive data: the urgency is lower, but you’re still on borrowed time.
When to Upgrade Windows 10 to Windows 11 in 2026: The Decision Tree
Use this framework to figure out where you stand:
Your PC was bought in 2022 or later: You almost certainly pass the Windows 11 compatibility check. Run PC Health Check to confirm, then upgrade for free via Windows Update. No hardware purchase needed.
Your PC was bought between 2019–2021: Mixed bag. Check your BIOS for a disabled TPM first — this is a free fix that works for many people in this category. If you have Intel 8th gen or AMD Ryzen 2000 series or newer, you’re likely compatible once TPM is enabled. If you have an older CPU, you may need hardware or a new build.
Your PC was bought before 2018: Your machine almost certainly fails the Windows 11 hardware requirements and cannot be bypassed officially. You have three choices: (1) stay on Windows 10 with an ESU license through October 2026, (2) explore Linux as a free alternative OS, or (3) build or buy a new machine. If you’re staying in the Windows ecosystem long-term, a new build is the cleanest path.
The Free Upgrade Path: How to Actually Do It
If your PC passes the compatibility check, upgrading is free and simpler than most people expect:
- Go to Settings > Windows Update > Check for Updates
- You’ll see an option to “Get Windows 11” if eligible
- Download and install — it typically takes 30–60 minutes
- Your files, programs, and settings are preserved
If Windows Update doesn’t offer the upgrade automatically, you can also download the Windows 11 Installation Assistant directly from Microsoft and run it manually. Both paths are fully legitimate and free for anyone on a licensed Windows 10 machine.
If you’re building a new PC from scratch or doing a clean install, you’ll want a Windows 11 Home OEM license — these run $30–$50 on Amazon and are the standard way to buy a standalone Windows license for a new build.
If You Need a New PC: The 2026 RAM Crisis Warning
If your Windows 10 machine truly can’t make the jump and you’re planning to build or buy a new one, you need to know about one major issue happening right now: RAM prices have surged dramatically in 2026. DDR5 32GB kits that cost $100–$120 in 2024 are now running $350–$440. This isn’t a blip — Gartner forecasts the surge to continue through year-end 2026. For a deep dive on what to buy and what to avoid right now, check our updated DDR5 RAM buying guide for 2026.
If you’re building, don’t wait. The general recommendation right now is to either:
- Build on AM5 with 16GB DDR5 — get a capable system now and add more RAM later when prices normalize. A solid starting point is pairing the Ryzen 5 9600X with the ASRock B860 Pro RS motherboard — both are competitively priced for the AM5 platform.
- Build on AM4 with 32GB DDR4 — DDR4 prices have barely moved, so 32GB kits are still under $90. This is the value play if you want maximum RAM now for minimum cost.
Don’t forget your storage. A good 1TB NVMe PCIe 4.0 SSD runs around $100–$110 and makes Windows 11 feel significantly snappier than any spinning hard drive. If your old PC had an HDD, upgrading to a modern NVMe drive — even in your existing system — can extend its usable life dramatically. See our best NVMe SSD picks for 2026 for current recommendations across every budget tier.

What About a Budget Laptop Instead?
If you’re not a gamer or power user — you just need a reliable Windows 11 machine for everyday tasks — a budget laptop may be a simpler path than building a desktop. Entry-level Windows 11 laptops with 8GB RAM and a 256–512GB SSD start around $350–$450. The trade-off is limited upgradeability; desktops are always the better long-term value if you’re comfortable building or can find a local builder.
Should You Switch to Linux Instead of Upgrading?
It’s worth at least considering. Ubuntu, Linux Mint, and Zorin OS are all free, actively maintained, and officially supported for years past Windows 10’s EOL date. If your PC is too old for Windows 11 and you primarily use it for web browsing, email, video streaming, and light office work — Linux handles all of that flawlessly and extends the life of aging hardware indefinitely.
The catch: if you rely on specific Windows-only software (certain business applications, some games), Linux is more friction than it’s worth for most users. But for simple home use on a pre-2018 machine, it’s a genuinely viable free alternative to a hardware purchase.
Final Verdict: What Should You Do?
Here’s the bottom line on whether to upgrade Windows 10 to Windows 11 in 2026:
- PC from 2022 or later: Upgrade for free right now. There’s no reason to wait.
- PC from 2019–2021: Check TPM in BIOS first. You may be compatible already. If not, evaluate whether the hardware cost of an upgrade makes sense vs. a new build in 1–2 years.
- PC from pre-2018: Plan a replacement. Your machine won’t get security updates past October 2026, and building new gives you a 5–7 year runway on modern hardware. Given current RAM prices, do this sooner rather than later.
- Just need more time: The Windows 10 ESU gives you coverage through October 2026. Use that window to plan and budget a hardware upgrade if needed.
The worst outcome here isn’t upgrading — it’s doing nothing and ending up on an unsupported OS without a plan. Whether that plan is a free OS upgrade, a BIOS tweak, a new SSD to breathe life into an older machine, or a full new build, you have options. Take advantage of them before the clock runs out.
Frequently Asked Questions
Is the Windows 11 upgrade still free in 2026?
Yes — if your PC meets Windows 11’s hardware requirements (TPM 2.0, compatible CPU, Secure Boot), the upgrade remains free through Windows Update or the Windows 11 Installation Assistant. Microsoft has not announced an end date for the free upgrade offer, but it is specifically for users coming from a licensed Windows 10 installation. Clean installs on new hardware require a paid license.
What happens to my files when I upgrade to Windows 11?
When you upgrade through Windows Update or the Installation Assistant, your personal files, installed applications, and settings are preserved. Microsoft refers to this as an in-place upgrade. That said, always back up important data before any OS upgrade — to an external drive or cloud storage — as a precaution against unexpected errors during installation.
Can I downgrade back to Windows 10 after upgrading?
Yes, but only within a limited window. Windows 11 gives you 10 days after upgrading to roll back to Windows 10 via Settings > System > Recovery. After that 10-day window closes, reverting requires a clean reinstall of Windows 10 using installation media, which would erase your current files. If you’re at all uncertain, back up everything before upgrading and test for a few days before the rollback window expires.
Is it safe to keep using Windows 10 after October 2026?
Technically possible, but increasingly risky. After October 13, 2026, Microsoft will release no further security patches for Windows 10. Any vulnerabilities discovered after that date remain permanently unpatched. Short term (a few months), risk is moderate if you practice safe browsing habits and run reputable antivirus software. Long term (a year or more), risk accumulates significantly. Using Windows 10 past EOL for banking, business, or anything with sensitive personal data is not recommended.
What is the cheapest way to get a legal Windows 11 license?
If you’re upgrading from Windows 10, it’s completely free — just run Windows Update or the Installation Assistant. If you need a new standalone license for a new build, Windows 11 Home OEM keys on Amazon typically run $30–$50 and are the standard route for DIY builders. Avoid third-party resellers offering Windows keys for under $15 — those are frequently sourced from volume license agreements and may be deactivated without warning.
