End of Windows 10 Support: What Defender Customers Need to Know
As of today, October 14, 2025, Microsoft is officially ending support for Windows 10. This means that Windows 10 devices will no longer receive security or feature updates, nor technical support from Microsoft. While these devices will continue to operate, the lack of regular security updates increases vulnerability to cyber threats, including malware and viruses. Applications running on Windows 10 may also lose support as the platform stops receiving updates. Will Defender continue to protect Windows 10 devices? Defender supports a range of legacy systems, including Windows 10. (See here for a full list of supported operating systems.) Microsoft Defender will continue to provide detection and protection capabilities to the extent possible on Windows 10 and other legacy systems. Keep in mind that security solutions on legacy systems are inherently less secure and may not be able to receive all new features, so please review the next section for important actions you can take. For Windows 10 customers without Defender, Microsoft will continue to provide security intelligence updates for the built-in Microsoft Defender Antivirus protection through October 2028. Of course, Defender Antivirus alone isn't a comprehensive risk mitigation posture without Microsoft Defender detection and response deployed across your digital estate. What should customers do to protect their Windows 10 devices? Upgrade to Windows 11: Moving to Windows 11 is strongly recommended for PCs eligible to upgrade. Windows 11 delivers the latest security features, improved performance, and ongoing support at no additional cost. This is the best way to ensure your endpoints remain protected and compliant. Devices running Windows 10 will be more vulnerable, even with ongoing security intelligence updates (SIUs). Extended security update (ESU) program: If upgrading isn’t immediately possible, Microsoft offers an ESU program for Windows 10. The ESU program provides critical and important security updates but does not include new Windows features or technical support. Enterprise customers can purchase ESU for up to three years or receive it at no additional cost with a Windows 365 subscription. Cloud and virtual environments: Windows 10 devices accessing Windows 11 Cloud PCs via Windows 365 or Virtual Machines are entitled to ESU at no extra cost, with automatic updates. Consumer customers have options to enroll for one year of ESU, including free enrollment methods in certain regions.

Request to Extend Windows 10 Support Beyond October 14, 2025
Hello Microsoft Team, I’m writing as a loyal Windows user to share my concern about the upcoming end of support for Windows 10 scheduled for October 14, 2025. Many users, including myself, rely on Windows 10 daily for work, education, and personal use. Not all of us are in a position to upgrade our hardware or switch to a new operating system without facing financial or technical challenges. Windows 10 is stable, familiar, and perfectly suits the needs of millions of people worldwide. I respectfully ask that Microsoft consider extending support for Windows 10 or providing more affordable and accessible options for users who cannot upgrade easily. Even an extended security update program for personal users (not just businesses) would make a big difference. Thank you for your time and for listening to the voices of your user community. Sincerely, Omar, Yahiya.
Windows 11 upgrade failed
Hello, on some of our devices the upgrade from windows 10 to 11 is failing, with the message of Undoing Changes Made to Your Computer, i can see some log files created in a folder Rollback etc but i cannot understand what is wrong and what is causing this. Can i upload the logs somewhere so you can check it and let me know what would be the issue?
Windows update in settings not showing up (something went wrong. Try open settings later)
i've had this problem a while now but didnt think much of it until i needed newer versions of windows to run apps. tried many ways like resetting settings to refresh. tried pc health check, troubleshoots which gave results that the problem was no identifiable. im not sure what i should do. i am trying to update to the lastest win 10 version as my pc does not support win 11.
ESU for W10 22H2 Not showing up??
I have W10 22H2 Home Edition, logged in as administrator with my MS account and all updates installed as of 12 today 10/10/25. Still no option for ESU?? Help. I spoke with an agent and he said, MS was delayed in working out issues. Anyone else? Getting really nervous....
Windows 10 ESU – Registrierungsbutton erscheint nicht trotz 22H2 (Rollout-Basis)
Hallo zusammen, ich möchte mein Windows 10 Pro-System für die Extended Security Updates (ESU) registrieren. Alle Voraussetzungen sind erfüllt (Version 22H2, Build 19045.6396, aktuelle Updates installiert, Microsoft-Konto aktiv). Trotzdem erscheint in Windows Update keine Schaltfläche „Jetzt registrieren“. Der Microsoft-Support hat mir heute bestätigt, dass der ESU-Rollout phasenweise fortgesetzt wird, auch nach dem 14. Oktober, nur Geräte unter 22H2 vom Supportende betroffen sind, und dass mein System automatisch berücksichtigt wird. Da ich mein Gerät gern rechtzeitig registrieren möchte, um Sicherheitsupdates nahtlos zu erhalten, meine Frage an das Entwicklerteam: Gibt es einen bekannten Zeitrahmen für den weiteren Rollout der ESU-Registrierung an 22H2-Geräte, oder spezifische Regionen- bzw. Kontoabhängigkeiten? Vielen Dank und viele Grüße MatthiasFile string limit check
Is there a report that can be run on Sharepoint to show file string size sorted highest to lowest? The issue we are running into is the difference between Sharepoint character limit and Windows Character limit. Out of the box they are different and Sharepoint's string limit is considerably higher. If there was a report, we could get a head of syncing issues.
