Windows 10 end of support: what it means and your options
Windows 10 stopped getting security updates on October 14, 2025. Every Windows 10 PC in your business is now unpatched. Here is what that means and how to handle the move to Windows 11.
Windows 10 reached the end of Microsoft support on October 14, 2025. Every PC still running it has stopped receiving security updates, which means new vulnerabilities will not be patched. For a business, that turns each Windows 10 machine into a growing risk and a likely problem at cyber insurance renewal. The fix is to move those devices to Windows 11, or replace the ones that cannot run it.
When did Windows 10 reach end of support?
Microsoft ended support for Windows 10 on October 14, 2025. After that date, Home and Pro editions no longer receive security updates or technical support. The PCs keep running, but they are no longer being protected against newly discovered threats.
Why does running Windows 10 now matter?
An unsupported operating system is a known, easy target. Attackers scan for unpatched machines, and the vulnerabilities they exploit often appear on the CISA Known Exploited Vulnerabilities list. Running out-of-support Windows can also break compliance and is increasingly a reason cyber insurers reduce or deny a claim.
Can my PCs run Windows 11?
Some can, some cannot. Windows 11 has stricter hardware requirements, including TPM 2.0 and a supported processor, so older machines may not be eligible to upgrade. The practical step is to inventory every device, upgrade the ones that qualify, and plan replacements for the ones that do not.
What should a business do now?
- Inventory every Windows 10 device and check Windows 11 eligibility
- Upgrade eligible machines to Windows 11 in planned batches
- Replace machines that cannot run Windows 11, ideally on a refresh schedule rather than all at once
- Confirm your other security controls, MFA, managed EDR, and backups, are in place while you transition

Frequently asked questions
- When did Windows 10 reach end of support?
- Windows 10 reached end of support on October 14, 2025. After that date, Home and Pro editions no longer receive security updates or technical support from Microsoft.
- Is it safe to keep using Windows 10?
- Not for a business. Without security updates, any new vulnerability stays open, which raises breach risk and can affect compliance and cyber insurance. The safe path is to move to Windows 11 or replace the device.
- Can all my computers upgrade to Windows 11?
- No. Windows 11 requires TPM 2.0 and a supported processor, so older machines may not qualify. You need to inventory each device, upgrade the eligible ones, and plan replacements for the rest.
- Does Windows 10 end of support affect cyber insurance?
- It can. Insurers increasingly expect supported, patched operating systems. Running out-of-support Windows can be a reason a policy is declined or a claim is reduced.

- Book a first appointment. We will inventory your devices, tell you which can upgrade and which need replacing, and roll out Windows 11 in batches that fit your schedule.
