Windows 10 end of life support arrived on October 14, 2025. Microsoft’s October security update was the last one for Windows 10, version 22H2 and the original 2015 LTSB releases. Devices will keep running, but they will no longer receive security updates, bug fixes, or technical support from Microsoft.
We know this change can feel disruptive. The good news is there are clear, practical next steps. Below you will find what changed, how it affects your organization, and what to do first.
What changed on October 14, 2025
- Final Windows 10 updates shipped. Microsoft ended support and monthly security updates for Windows 10, version 22H2.
- Older long‑term editions also reached the end. Windows 10 Enterprise 2015 LTSB and Windows 10 IoT Enterprise LTSB 2015 exited support on the same date.
- Your PCs still work, but risk grows. After end of support, Microsoft no longer provides security patches or technical assistance, which increases exposure to threats over time.
Note: Long-Term Servicing Branch/Channel (LTSB/LTSC) editions follow different lifecycle rules by release. Always confirm dates on Microsoft’s lifecycle site.
What this means for your organization
This Windows 10 end of life support milestone affects security, compliance, and day‑to‑day reliability:
- Security exposure rises because newly discovered vulnerabilities will not be patched on unsupported devices.
- Compliance risk increases in regulated industries that require supported operating systems. (Microsoft’s lifecycle policy is the reference for auditors.)
- There is a bridge option. If you must keep certain PCs on Windows 10 for now, Microsoft’s Extended Security Updates (ESU) program can provide paid critical updates for eligible devices running Windows 10, version 22H2. Commercial customers can enroll for up to three years of security updates.
What to do next
- Identify impacted devices. Create a quick list of PCs still on Windows 10 and note versions. Prioritize systems that touch sensitive data.
- Upgrade where possible. Move eligible devices to Windows 11 to regain full security and feature updates.
- Enroll holdouts in ESU. For devices that cannot upgrade yet, enroll Windows 10 version 22H2 machines in Microsoft’s ESU program to maintain security coverage while you finalize migration plans.
- Plan hardware refresh. If older hardware does not meet Windows 11 requirements, schedule phased replacements to avoid downtime and rushed purchases. Our procurement team can help you acquire the right devices at a price point that works for your company.
