As of this date, no security updates or patches will be released, exposing your systems remaining on this version to unpatched vulnerabilities. New vulnerabilities discovered by attackers will provide them with a new entry point into your IS. We therefore urge you to take action as soon as possible. ## **What can you do?** **Upgrade to Windows 11:** This is the most recommended option for benefiting from the latest features, extended support and enhanced security. Under Windows 11, patches will protect you from the exploitation of new vulnerabilities! **ESU Program (Extended Security Updates):** This is a paid option offered by Microsoft that enables you to continue receiving security updates for Windows 10 after the official end of support, for up to three years. It's a temporary solution to buy a little time to complete migrations to the latest Windows OS. However, you'll need to**carefully assess the cost**: $61 per workstation for the first year, $122 for the second and $244 for the third - a rate that doubles every year, to encourage you to migrate as soon as possible. **Lastly, if** you are unable to upgrade your system (due to hardware or production constraints),**isolating it from the rest of the information system** is a compensatory measure designed to limit the impact of any compromise. This isolation must be carried out as quickly as possible. ## **How to migrate smoothly?** **Hardware requirements :** Windows 11 requires machines to have certain technical characteristics. You can check your workstations with the following little tool: [PC Integrity Check](https://support.microsoft.com/fr-fr/windows/v%C3%A9rifier-si-un-appareil-r%C3%A9pond-%C3%A0-windows-11-configuration-requise-apr%C3%A8s-avoir-modifi%C3%A9-le-mat%C3%A9riel-de-l-appareil-f3bc0aeb-6884-41a1-ab57-88258df6812b) **New machine or simple upgrade:** - If current hardware is compatible, a direct upgrade to Windows 11 is possible. - If the hardware doesn't meet the requirements, a new machine should be considered. **Licensing:** Migration to Windows 11 may require a license upgrade, depending on the type of contract (OEM, Volume Licensing, Microsoft 365, etc.). To ensure that your migration goes as smoothly as possible, we recommend that you **carry out a workstation compatibility audit as soon as possible**, draw up a Windows 11 migration timetable, and define the strategy for non-compatible machines (replacement or temporary use of the ESU). This anticipation will guarantee security, compliance and continuity of operations beyond the end of support. ## To find out more : - [CERT FR notification](https://www.cert.ssi.gouv.fr/actualite/CERTFR-2025-ACT-017/) - [Lifecycle - W10 Enterprise & Education](https://learn.microsoft.com/fr-fr/lifecycle/products/windows-10-enterprise-and-education) - [Lifecycle - W10 Home & Pro](https://learn.microsoft.com/fr-fr/lifecycle/products/windows-10-home-and-pro) - [Planning W11 migration](https://learn.microsoft.com/fr-fr/windows/whats-new/windows-11-plan?context=%2Fwindows%2Fdeployment%2Fcontext%2Fcontext) - [W11 hardware requirements](https://learn.microsoft.com/fr-fr/windows/whats-new/windows-11-requirements) Cyber risk is the number 1 risk for any company, whatever its size. ## Articles similaires [ How to Create and Manage Truly Effective Passwords 23 April 2026 ](https://www.dattak.io/en/blog/dattak-blog-bonnes-pratiques-mot-de-passe?hsLang=en) [ Professional Liability vs. Cyber Insurance: Why These Products Are Different… Yet Inseparable 23 April 2026 ](https://www.dattak.io/en/blog/dattak-blog-rcpro-vs-assurance-cyber?hsLang=en) [ Cyberattacks - A Look Back at the First Quarter of the Year! 23 April 2026 ](https://www.dattak.io/en/blog/dattak-premier-trimestre-attaques?hsLang=en) ## Prenez le contrôle de vos risques technologiques La meilleure défense, c'est Dattak.
