Quick answer: In the Windows 11 vs Windows 10 decision, Windows 11 is now the clear choice for most people because Windows 10 reached end of support on October 14, 2025 and no longer gets free security updates by default. If your PC meets the requirements, upgrade to Windows 11; if it does not, consider the Extended Security Updates program to stay protected while you plan a move.
The Windows 11 vs Windows 10 conversation has changed completely. For years it was a matter of taste, but the calendar has forced the issue. Windows 10 hit its official end-of-support date in October 2025, which reshapes the math for anyone still weighing whether to upgrade. In this guide I compare the two systems on the things that actually matter, explain what “end of support” really means for your safety, and help you decide what to do next.
Windows 11 vs Windows 10: the key differences
Here is a side-by-side look at the factors people ask about most, from support timelines to hardware requirements.
| Factor | Windows 11 | Windows 10 |
|---|---|---|
| Security updates | Ongoing and free | Ended Oct 14, 2025 (paid/ESU only after) |
| Hardware requirements | Stricter (TPM 2.0, newer CPUs) | Looser; runs on older PCs |
| Interface | Centered taskbar, rounded, refreshed | Traditional left-aligned Start |
| New features | Snap Layouts, better multitasking, AI/Copilot tools | Feature-frozen |
| Cost to upgrade | Free from eligible Windows 10 PCs | N/A |
| Best for | Almost everyone with supported hardware | Older PCs that cannot upgrade (with ESU) |
The most important difference: support has ended for Windows 10
This is the headline. Microsoft ended free support for Windows 10 on October 14, 2025. After that date, Windows 10 stopped receiving the regular security updates, bug fixes, and technical assistance that keep a system safe. Your Windows 10 PC still turns on and runs your programs, but every month that passes without patches, newly discovered vulnerabilities go unaddressed, and the security risk grows.
That is why the upgrade question is now really a security question. Running an unsupported operating system connected to the internet is a genuine risk for malware and data theft, especially for the kind of everyday banking, shopping, and email most of us do.
What about Extended Security Updates (ESU)?
Microsoft created a bridge called the Extended Security Updates program so people are not left stranded. For consumers, ESU delivers critical and important security patches beyond the end-of-support date while you transition to a newer PC. Microsoft has expanded this consumer option, and its guidance has pointed to coverage running into October 2027, with enrollment open until the program ends.
A few caveats to keep in mind, since Microsoft has adjusted these terms more than once:
- ESU covers Windows 10 version 22H2 specifically, so make sure you are on that version.
- ESU provides security updates only, not new features, general bug fixes, or technical support.
- Exact enrollment details and pricing can vary, so confirm the current terms on Microsoft’s official ESU page before relying on them.
Think of ESU as a temporary safety net, not a permanent home. It buys you time to plan a graceful move rather than a reason to stay on Windows 10 indefinitely.
Interface and everyday experience
Beyond security, the two systems feel different day to day. Windows 11 introduced a centered, cleaner look with a redesigned Start menu, rounded window corners, and a more modern Settings app. Windows 10 keeps the familiar left-aligned Start button that longtime users have muscle memory for.
Windows 11 also added genuinely useful productivity touches:
- Snap Layouts for arranging windows into tidy grids in a couple of clicks.
- Improved virtual desktops and multitasking for people who juggle many apps.
- Integrated Copilot and AI features that Microsoft continues to build out, which Windows 10 does not receive.
None of these are life-changing on their own, but together they make Windows 11 feel like the version Microsoft is actively investing in, because it is.
Hardware requirements: the real sticking point
The biggest reason someone stays on Windows 10 is not preference, it is eligibility. Windows 11 requires TPM 2.0, Secure Boot, and a relatively modern processor, and plenty of otherwise-capable PCs from the late 2010s do not qualify. To check your own machine, use Microsoft’s PC Health Check app, which tells you whether your device is eligible and, if not, why.
If your PC is eligible, the upgrade from a genuine Windows 10 license is free and your files and apps come along. If it is not eligible, your realistic options are to enroll in ESU for interim protection, buy a new Windows 11 PC, or explore an alternative operating system such as a Linux distribution for older hardware you want to keep using.
So which should you use?
For the overwhelming majority of readers, the answer is Windows 11. It is supported, it is free to upgrade to from an eligible Windows 10 machine, and it is where all future features and security work are happening. Windows 10 only makes sense as a short-term situation for hardware that cannot make the jump, and even then you should pair it with ESU and a plan to move on.
Frequently asked questions
When did Windows 10 support end?
Windows 10 reached end of support on October 14, 2025. After that date it no longer receives free security updates, feature updates, or technical assistance from Microsoft by default.
Can I still use Windows 10 safely after end of support?
You can keep using it, but it becomes progressively riskier as unpatched vulnerabilities pile up. Enrolling in the Extended Security Updates program keeps critical security patches flowing during the transition and is the safer way to stay on Windows 10 for now.
How long does the Windows 10 ESU program last?
Microsoft’s consumer ESU option extends security coverage past the 2025 cutoff, with guidance pointing to availability into October 2027 and enrollment open until the program ends. Because Microsoft has revised these terms, check the official ESU page for the exact current dates and requirements.
Is upgrading to Windows 11 free?
Yes, if your PC runs a genuine, activated copy of Windows 10 and meets the hardware requirements, the upgrade to Windows 11 is free. Your files and installed apps carry over during the process.
How do I know if my PC can run Windows 11?
Run Microsoft’s free PC Health Check app. It checks for TPM 2.0, Secure Boot, and a supported processor, then tells you whether your device is eligible and what is blocking the upgrade if it is not.
What if my computer cannot run Windows 11?
Your practical choices are to use ESU for temporary protection, buy a new Windows 11 PC, or switch that older machine to a lightweight Linux distribution. Running Windows 10 unprotected online long term is not recommended.
The bottom line
The Windows 11 vs Windows 10 question is largely settled by the calendar: with Windows 10 out of free support since October 14, 2025, Windows 11 is the right home for any PC that can run it, and the upgrade is free from an eligible machine. If your hardware cannot make the leap, lean on the Extended Security Updates program as a bridge while you plan for a newer device, rather than leaving an unsupported system exposed online.
