Windows 10 will stop receiving security updates on October 14, 2025
If you do not upgrade to Windows 11, your computer will continue to work on Windows 10, but Microsoft will stop releasing security patches after October 14, 2025. This means any new vulnerabilities discovered after that date will not be fixed on your machine. Your system will become increasingly exposed to malware, ransomware, and other threats that exploit those unpatched weaknesses.
You can keep using Windows 10 after the cutoff date — the operating system will not shut down or lock you out. But each month that passes without updates makes your computer a more attractive target for attackers. If you use your computer for banking, email, or any activity involving passwords or personal information, staying unpatched creates real risk.
Key Takeaways
- Windows 10 support ends October 14, 2025, and Microsoft will no longer release security updates after that date.
- Your computer will continue to function after the cutoff, but new security vulnerabilities will go unfixed.
- Windows 11 requires specific hardware, and some older computers cannot run it even if you want to upgrade.
- If your computer cannot run Windows 11, you can continue using Windows 10 at your own risk, or replace the hardware.
- Staying on Windows 10 after the cutoff is most dangerous if you use the computer for financial transactions or store sensitive files.
Your computer will keep running, but without protection
The end of support does not mean your computer stops working. Windows 10 will function exactly as it does now — you can open files, run programs, and connect to the internet. What changes is that Microsoft's security team will no longer investigate or patch newly discovered flaws in the operating system itself.
Think of it like a building with a security system that stops being monitored. The locks still work, the doors still open, but nobody is watching for break-ins anymore. If a burglar finds a new way in, there is no one to fix it. The longer you go unpatched, the more methods attackers have available to exploit.
Software you install separately — like Chrome, Firefox, or Microsoft Office — may continue to receive updates from their own makers. But the foundation underneath them, Windows 10 itself, will be frozen in time.
Windows 11 has hardware requirements that older computers cannot meet
Many people cannot upgrade to Windows 11 because their computer does not meet the minimum hardware requirements. Windows 11 requires a processor from roughly 2017 or newer, at least 4 GB of RAM, and a specific type of firmware called UEFI. It also requires a security chip called TPM 2.0, which many older machines do not have.
You can check whether your computer can run Windows 11 by downloading Microsoft's PC Health Check tool from their website and running it. The tool will tell you exactly which requirements your machine fails to meet. If your computer is more than five or six years old, there is a good chance it will not may have access to.
If your hardware cannot run Windows 11, you have two main paths: continue using Windows 10 at increased risk, or replace your computer with one that meets Windows 11's requirements.
Malware and ransomware become more dangerous over time
Attackers do not immediately exploit every security flaw they find. Many vulnerabilities are discovered by security researchers or reported by users, and Microsoft patches them before widespread attacks begin. But once Windows 10 support ends, those researchers and users will have no reason to report flaws to Microsoft — there will be no patch coming.
Ransomware attacks, which lock your files and demand payment to unlock them, often target computers running outdated operating systems. Criminals know that unpatched machines are easier to break into. If you store important documents, photos, or financial records on your computer, an unpatched Windows 10 system puts those files at real risk.
The danger is not immediate or certain — you might use an unpatched computer for years without being attacked. But the odds get worse every month, and the cost of being wrong is high.
Banks and websites may stop supporting Windows 10
Some banks, financial services, and websites have already begun requiring Windows 11 or at least a current version of Windows 10 with the latest updates. As Windows 10 support ends, more organizations may drop support for it entirely. You might find that you cannot access your bank's website, cannot update certain software, or cannot use services that require current security standards.
This is not universal — many websites and services will continue to work on older systems for years. But the trend is moving away from supporting outdated operating systems, and the further you get from the support cutoff date, the more services may become unavailable to you.
What to do if you want to stay on Windows 10
If you decide to keep using Windows 10 after October 14, 2025, take steps to reduce your risk. Use a strong, unique password for every online account. Enable two-factor authentication wherever it is offered. Keep your web browser and other software updated, even though Windows itself will not be. Consider using antivirus software beyond what Windows Defender provides.
Avoid opening email attachments from unknown senders, and be cautious about clicking links in emails or messages. Do not use your unpatched computer for sensitive financial transactions if you can avoid it — use a phone or a newer computer for banking instead. Back up your important files regularly to an external drive or cloud storage, so that a ransomware attack does not destroy them.
These steps reduce risk but do not eliminate it. They are a holding pattern, not a permanent solution.
Replacing your computer may be cheaper than you think
If your computer cannot run Windows 11, you have the option to buy a new one. A basic Windows 11 laptop or desktop that meets the hardware requirements costs between $300 and $600 new. Refurbished computers that are one or two years old often cost $200 to $400 and work reliably.
If you use your computer for work or for anything involving financial information, the cost of a new machine is often less than the cost of recovering from a ransomware attack or identity theft. A single breach can cost thousands in recovery, fraud monitoring, and lost time.
Frequently Asked Questions
Can I upgrade to Windows 11 on my current computer?
Not necessarily. Download Microsoft's PC Health Check tool and run it to see whether your hardware meets Windows 11's requirements. If it does not, upgrading is not possible without replacing your computer. If it does, you can purchase a Windows 11 license and perform the upgrade yourself, or take your computer to a repair shop to have it done.
What if I use my computer for work only, not for banking or sensitive information?
The risk is lower, but not zero. Ransomware can still encrypt your work files and make them unusable. If your employer requires you to use current security standards, they may not allow you to use an unpatched computer on their network. Check your company's policy before deciding to stay on Windows 10.
Will Windows 10 suddenly stop working on October 14, 2025?
No. Your computer will continue to work exactly as it does now. The only change is that Microsoft will no longer release security updates. The operating system itself will not shut down or become unusable.
Is Windows 11 worth upgrading to if my computer can run it?
If your hardware supports Windows 11, upgrading before October 2025 is the safest choice. You will receive security updates until at least 2032, and you will avoid the risk of using an unpatched system. The upgrade itself is usually free if you already own a Windows 10 license.
Can I use Linux or Mac instead of Windows 11?
Yes, if you are willing to learn a different operating system and make sure your software works on it. Linux is free and runs on older hardware. Mac computers run macOS, which receives updates for several years. Both are valid alternatives if you want to avoid Windows 11, but they require more technical knowledge than staying on Windows.
