The Windows 10 End of Support Deadline
Microsoft marked a major milestone for Windows 10: regular support ends on October 14, 2025. After that date, standard feature updates stop, and security updates are limited to the Extended Security Update (ESU) program under specific conditions. The ESU window runs from October 15, 2025 to October 13, 2026, giving many users a last, finite period to stay protected while exploring alternatives.
What is the Extended Security Update (ESU) program?
The ESU program is designed for devices that cannot or will not immediately move to Windows 11 or another operating system. It provides continued access to critical security updates for Windows 10 during the defined window. As part of the rollout, Microsoft introduced two paths: a one-time enrollment fee and a potential free option for certain users who sign in with a Microsoft account (MSA) and remain signed in. An ESU setup assistant is expected to appear in Windows 10 settings in early October to guide users through enrollment. Participation is voluntary, and there is no obligation to join.
Who qualifies and how to check your system?
Eligibility largely depends on your device running Windows 10 and meeting basic activation criteria. To see if you are affected or eligible for ESU, check your Windows version and edition by right-clicking the Start button, selecting System, then looking under Windows specifications. If you are unsure about upgrade options, Microsoft offers the PC Health Check tool to confirm whether your hardware would support Windows 11, even if you plan to stay on Windows 10 for now.
Upgrading to Windows 11 or choosing another path
Microsoft continues to offer a free upgrade path from Windows 10 to Windows 11 for devices that meet minimum hardware requirements (including TPM 2.0, at least 4 GB RAM, and compatible processors). If PC Health Check indicates compatibility, you can proceed via Windows Update. If not, several steps can often help: enable TPM and Secure Boot in the UEFI/BIOS, switch to UEFI boot mode, and, if needed, convert the disk from MBR to GPT using the official mbr2gpt tool. After these changes, retake the PC health check to see if Windows 11 becomes available.
What if Windows 11 still isn’t offered?
In some cases the upgrade remains blocked. Advanced techniques exist, such as creating a bootable Windows 11 installer with a tool like Rufus to bypass some requirements. These methods carry risk and require thorough data backups before attempting them.
Other options if your device isn’t Windows 11-ready
If upgrading is not feasible, moving to an operating system that continues to receive security updates is often the most practical long-term solution. Linux distributions such as Linux Mint, Zorin OS, or Ubuntu offer robust security updates and broad hardware support. For Windows users, Linux can provide a familiar desktop experience with extensive documentation, easing the transition.
How to prepare today
Regardless of the chosen path, back up important data to an external drive before making major changes. Review firmware and BIOS/UEFI settings, ensure updates are current, and consider hardware upgrades if you plan to stay with Windows 11 or a newer OS. Remember that ESU commitments run only through October 2026. Planning a migration to Windows 11 or another OS ahead of time minimizes risk and cost in the long run.
Cost and practical considerations
The ESU option includes a one-time enrollment fee (reported as $30 per device) in some regions, with a free path possible for users signed in with a Microsoft account. If you rely on ESU, keep in mind it is a transitional measure, not a permanent replacement for a full OS upgrade. IT teams and households should weigh ESU against planned hardware refreshes and a long-term OS strategy.
For IT admins and households
Inventory devices, track eligibility for ESU, and decide whether to migrate to Windows 11, another Windows edition, or a Linux-based system. Test backups, verify driver support, and prepare a rollout plan that minimizes downtime. If you need help, consult Microsoft support or trusted IT partners to design a sustainable path beyond 2026.
