Windows 10 will stop receiving security updates on October 14, 2025

If you do not move to Windows 11, your computer will continue to work after that date — it will not suddenly stop or lock you out. But Microsoft will stop releasing security patches for Windows 10. That means new viruses, malware, and exploits discovered after October 2025 will have no patch available for your machine. Your computer becomes increasingly vulnerable the longer you go without updates.

This is the hard deadline. Windows 10 launched in 2015 and received ten years of support, which is longer than most operating systems get. After October 2025, you are on your own for security.

Key Takeaways

  • Windows 10 stops receiving security updates on October 14, 2025, leaving your computer exposed to new threats with no patches available.
  • Your computer will still turn on and run programs after the deadline, but you will be responsible for protecting it against viruses and hacks.
  • Windows 11 requires specific hardware — mainly a processor from 2017 or newer and a chip called TPM 2.0 — and many older computers cannot run it.
  • If your computer cannot run Windows 11, you can stay on Windows 10 with extra caution, switch to a different operating system, or replace the hardware.
  • Waiting until October 2025 to decide leaves you scrambling; planning now gives you time to test Windows 11 or explore other options.

Why Windows 11 will not install on your computer

Windows 11 has strict hardware requirements that rule out many machines built before 2017. The main blockers are the processor (CPU) and a security chip called TPM 2.0. If your computer has an Intel processor older than 8th generation or an AMD Ryzen older than 2000 series, Windows 11 will refuse to install. Many laptops and desktops from 2015 to 2017 fall into this category.

You can check your processor by right-clicking "This PC" or "My Computer" on your desktop, selecting Properties, and looking for the processor name. If it says "Intel Core i5-7500" or older, or "AMD Ryzen 1600" or older, Windows 11 is not an option for your hardware. The same applies if your computer lacks TPM 2.0, which you can verify through Device Manager — search for "tpm" in the Windows search box and look for "Trusted Platform Module 2.0".

This is not a limitation you can work around with a software patch. Windows 11 simply will not install on incompatible hardware, and Microsoft has not announced plans to change this requirement.

The real security risk of staying on Windows 10

After October 2025, every new vulnerability discovered in Windows 10 becomes a permanent hole in your computer. Hackers publish exploits for unpatched systems, and malware authors build tools to attack them. Your machine becomes a target not because it is special, but because it is known to be undefended.

The risk is not theoretical. In 2016, Microsoft stopped supporting Windows 7, and within months, ransomware authors began targeting it specifically because they knew no patches would arrive. Hospitals, banks, and government agencies that stayed on Windows 7 became victims. The longer you run an unsupported system, the more likely you are to encounter malware designed for it.

This does not mean your computer will be hacked immediately. It means the odds increase every month. A virus that spreads in November 2025 will have no patch. A new ransomware variant in 2026 will work on Windows 10 with certainty. You are betting that you will not be the one hit.

Your options if Windows 11 will not run on your hardware

You have three realistic paths: stay on Windows 10 with heightened caution, switch to a different operating system, or replace the hardware.

Staying on Windows 10 with extra protection means treating your computer like a machine that is no longer your responsibility to defend. Do not use it for banking, shopping, or anything involving passwords or payment information. Do not open email attachments from people you do not know. Do not visit untrusted websites. Run a paid antivirus program — Windows Defender will not be updated either, so a third-party tool like Bitdefender or Kaspersky becomes your only defense. Even then, you are relying on antivirus to catch threats after they arrive, not on Windows to prevent them. This approach works for machines used only for web browsing and email on a trusted network, but it is not safe for anything sensitive.

Switching to a different operating system is possible if your computer can run Linux or macOS. Linux is free and runs on older hardware than Windows 11 requires. It has a smaller target for malware because fewer people use it, though it is not immune. macOS is an option only if you own a Mac, and Apple also stops supporting older machines — but usually later than Microsoft does. Both systems have a learning curve if you are used to Windows.

Replacing the hardware is the most straightforward path if you can afford it. A new computer with Windows 11 pre-installed costs between $400 and $800 for a basic laptop or desktop. You get a machine with current security, longer support ahead, and better performance. If your current computer is five or more years old, replacement is often cheaper than the risk of staying unpatched.

What to do right now if you are unsure about Windows 11

Test Windows 11 before October 2025 arrives. If your computer meets the hardware requirements, download the Windows 11 installation media from Microsoft's website and create a bootable USB drive. You can run Windows 11 from the USB without installing it, which lets you see whether your programs work and whether you like the interface. This takes an hour and costs nothing.

If your computer cannot run Windows 11, decide now whether you will replace it, switch operating systems, or stay on Windows 10 with restrictions. Do not wait until October 2025 to figure this out — you will be rushed, prices may be higher, and you will have no time to learn a new system before your current one becomes unsafe.

Back up your files regardless of what you choose. If you stay on Windows 10, keep backups on an external drive that you disconnect after each backup — ransomware cannot encrypt a drive that is not connected. If you switch systems or replace hardware, you will need those files on the new machine.

Programs and files will work the same way after October 2025

Your Microsoft Office documents, photos, and programs will not disappear or stop working on October 14, 2025. The date is not a switch that turns off your computer — it is the date when Microsoft stops sending security updates. Your email will still arrive. Your spreadsheets will still open. Your printer will still print.

What changes is that you are no longer protected. Every program you run, every file you open, every website you visit becomes a potential entry point for malware. The longer you go without updates, the more entry points exist. Your computer does not know it is unsupported — it just becomes increasingly unsafe.

Frequently Asked Questions

Can I pay Microsoft to keep getting Windows 10 updates after October 2025?

No. Microsoft offers extended support for businesses and enterprises, but not for individual consumers. If you own the computer personally, October 2025 is the final date for any updates.

Will my programs stop working if I upgrade to Windows 11?

Most programs work on Windows 11, but some older software may not. Before upgrading, check the software maker's website or test on a USB drive. If a critical program does not work on Windows 11, that is a real reason to explore other options.

Is Windows 11 slower than Windows 10?

On newer hardware, Windows 11 performs similarly to Windows 10. On older hardware that barely meets the minimum requirements, it may feel slower. This is another reason to test it first if you are unsure.

What if I just use my computer offline after October 2025?

An offline computer is safer than a connected one, but not completely safe. Malware can spread through USB drives, external hard drives, and any removable media. If you never connect to the internet and never use external drives, the risk drops significantly — but this is impractical for most people.

Can I downgrade from Windows 11 back to Windows 10?

Yes, but only within 10 days of upgrading. After that, you would need to reinstall Windows 10 from scratch, which erases everything on your computer. Plan carefully before upgrading if you think you might want to go back.
