Yes—your Windows 10 PC will keep starting and running after security updates end. The important change is that Microsoft no longer supplies the operating-system security fixes, feature updates, or normal technical assistance for Windows 10 version 22H2. That leaves you with three practical choices: upgrade an eligible PC to Windows 11, use any Extended Security Updates (ESU) offer your device and market still show, or replace the computer. You can continue without updates, but you are accepting greater exposure to malware and viruses.
What “end of support” actually means
Windows 10 version 22H2 reached the end of its ordinary support period on October 14, 2025. End of support is not a remote shutdown or an expiration date for the operating system. Your installed programs, files, printers and hardware can continue to work. The change is Microsoft’s maintenance obligation: the covered Windows version no longer receives its regular operating-system security fixes, feature updates or technical assistance.

A computer can therefore remain usable while becoming harder to defend. New vulnerabilities discovered after the cutoff may not receive a Windows 10 fix, and compatibility problems that would previously have been addressed through supported updates may remain unresolved.

Will my Windows 10 computer stop working?
No. Microsoft says Windows 10 PCs continue to function after support ends. You should still be able to sign in, open installed applications and access your files. Some individual applications, drivers, websites or online services can impose their own requirements, however, so “the PC still runs” does not guarantee that every future program will continue to support it.

Why continuing without operating-system fixes is a security trade-off
Security software can block many known threats, but the operating system is part of the security boundary. Windows updates repair vulnerabilities in components such as authentication, networking, file handling and the browser platform. If those components are no longer patched, an attacker may be able to exploit a weakness before antivirus software recognizes the behavior.
Microsoft’s support guidance describes an unsupported Windows 10 PC as being at “a greater risk for viruses and malware.” That is a qualitative warning, not a prediction of your personal probability of compromise. Risk depends on factors such as whether the PC is exposed to the internet, how current applications are, which accounts are used and whether unsafe files or links are opened.
Can I just use antivirus software to stay protected?
Not completely. Microsoft states that antivirus products, including Microsoft Defender or third-party tools, can help but are “not enough on its own” when Windows no longer receives security fixes. Keep antivirus enabled and current, but treat it as one layer rather than a replacement for a supported operating system.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- Install application and browser updates that remain available.
- Use a standard user account for everyday work when practical, reserving administrator access for tasks that need it.
- Turn on multifactor authentication for important online accounts.
- Keep reliable, offline or otherwise protected backups of documents and photos.
- Be cautious with unexpected attachments, downloads, macros and links.
Microsoft 365 support does not extend Windows 10 support
Microsoft says Microsoft 365 Apps continue to run on Windows 10 and receive application security updates through October 10, 2028. That commitment applies to the Microsoft 365 applications, not to the Windows 10 operating system underneath them.
In practice, Word, Excel, Outlook and other Microsoft 365 programs may continue receiving fixes while an unpatched Windows component remains exposed. Microsoft recommends moving to a supported Windows release to avoid performance and reliability problems that can accumulate over time. Do not interpret an updated application as proof that Windows itself is still being secured.
First step: check whether your PC can upgrade to Windows 11
Eligibility is specific to the hardware and configuration of each computer. Microsoft directs eligible Windows 10 devices to the Windows 11 upgrade through Windows Update.
- Save your work and make a current backup of important files.
- Open Settings, then Update & Security, and choose Windows Update.
- Install any remaining Windows 10 updates shown, then select the option to check for a Windows 11 upgrade if it is offered.
- If Windows Update does not offer the upgrade, use Microsoft’s PC Health Check flow to see whether the device meets Windows 11 requirements and which requirement is blocking it.
- Review available storage, application compatibility and backup status before accepting the upgrade.
An upgrade offer is the clearest indication that Microsoft considers the device eligible through the normal consumer path. If the hardware is ineligible, repeatedly forcing an unsupported installation does not restore the security support that the device lacks.

Your three practical paths
| Path | Best fit | Security coverage | Main trade-off |
|---|---|---|---|
| Upgrade the existing PC to Windows 11 | A Windows 10 PC that passes Microsoft’s compatibility checks | Moves the device to a supported Windows release, subject to that release’s lifecycle | Requires compatibility checks, available storage and time for the upgrade; older peripherals or applications may need attention |
| Consumer Extended Security Updates | An eligible personal-use Windows 10 version 22H2 device when the current enrollment screen offers it | Critical and important Windows security updates for the ESU term; it is not full Windows support | Limited duration, regional eligibility and enrollment conditions; it does not add feature updates or normal technical assistance |
| Replace the computer with a Windows 11 PC | Hardware that cannot meet Windows 11 requirements, or a user who needs a longer supported life without an upgrade migration | The new installation starts on a supported Windows 11 device | Highest upfront cost and the work of transferring files, applications, settings and peripherals |
| Keep running Windows 10 without ESU | A short-term or tightly controlled use case where the owner accepts the exposure | No ordinary Windows 10 operating-system security fixes after the support cutoff | Growing vulnerability to unpatched flaws and no Microsoft fix for newly discovered Windows 10 issues |
Extended Security Updates: what they cover and what they do not
Microsoft’s detailed consumer FAQ says eligible Windows 10 version 22H2 devices can receive critical and important security updates through October 13, 2026. Consumer enrollment terms can vary by market. The FAQ describes these enrollment routes:
- Enrollment through synchronized PC settings at no additional cost.
- Redemption of 1,000 Microsoft Rewards points.
- A one-time payment of $30 USD plus applicable tax.
These terms are for eligible personal-use devices in supported markets. Microsoft says consumer ESU is generally available in most markets but excludes organization-managed or enterprise-licensed devices. A work-managed computer, a computer covered by a commercial agreement or a different Windows edition may follow different rules.
Why you should verify the date on your own enrollment screen
Microsoft’s overview material has also stated that consumer ESU can protect a Windows 10 device until October 12, 2027, while the detailed consumer FAQ gives October 13, 2026 as the coverage date. The published pages do not explain the difference. Because the October 13, 2026 date has passed as of this article’s publication date, do not assume that a previously advertised term is still available. Open the current Windows enrollment experience for your device and location and read the term shown there before paying or relying on ESU.
ESU is a temporary security bridge. It does not turn Windows 10 into a fully supported feature branch, provide a Windows 11 upgrade, or guarantee that every application and peripheral will remain compatible.

Replacement is not mandatory merely because Windows 10 support ended. It becomes more compelling when the computer fails the Windows 11 checks, is already unreliable, or contains hardware that is expensive to repair. A new Windows 11 laptop or desktop can reduce migration complexity compared with trying to keep an incompatible installation in service.
Before buying, list the work the current computer performs: applications, printers, scanners, displays, storage devices and any specialized accessories. Confirm that each has a Windows 11-compatible driver or replacement. Back up files, sign out of accounts, transfer licenses where required and securely erase or recycle the old machine only after you have verified the new one.
How to keep an unsupported PC safer if you must use it temporarily
Running without operating-system updates is the least secure option, but practical constraints sometimes make it unavoidable for a short period. Reduce exposure rather than treating these measures as equivalent to support:
- Disconnect the PC from the internet when its task does not require network access.
- Use it for a narrow, known purpose instead of general browsing, banking or handling sensitive accounts.
- Keep the browser, PDF reader, office suite and other applications at their latest supported versions.
- Remove software you no longer need and disable unnecessary startup tools or remote-access services.
- Use a separate, supported device for password management, financial activity and other high-value accounts.
- Maintain tested backups that cannot be overwritten by ransomware on the Windows 10 machine.
- Do not install unofficial “security update” packages that claim to replace Microsoft’s servicing process.
These controls lower some avenues of attack; they cannot patch a vulnerability in Windows itself. Set a deadline for upgrading, enrolling in an available ESU term or replacing the device instead of allowing a temporary exception to become permanent.
A decision checklist
- Identify the edition and version. Confirm that the computer is running Windows 10 version 22H2 and determine whether it is personal-use, organization-managed or covered by an enterprise license.
- Check Windows Update. Look for an offered Windows 11 upgrade and record any compatibility message.
- Assess how long you need the PC. A brief bridge may justify investigating ESU; a multi-year need usually favors a supported Windows 11 installation.
- Check the current ESU offer. Review the enrollment screen for your market, device and edition rather than relying on an old date or a general web statement.
- Price disruption, not just hardware. Include data migration, application licenses, peripherals and the time needed to configure a replacement.
- Protect data before changing anything. Verify a restorable backup before upgrading, enrolling or replacing the computer.
The bottom line for Windows 10 owners
Your PC can remain usable after Windows 10 security updates end, but its security position changes immediately when the operating system stops receiving fixes. Check for a supported Windows 11 upgrade first. If the device is ineligible, compare the current consumer ESU offer with the cost and disruption of replacement, paying attention to your market and the date shown by Microsoft. Antivirus, application updates and careful habits are worthwhile layers, not substitutes for a supported operating system.
