"While we work to address the issue, admins in impacted organizations may be able to circumvent impact by pausing Windows Feature Updates until the code fix has been developed, tested, and deployed," Microsoft said. Redmond acknowledged the issue after days of widespread reports from Windows admins that servers in their organizations' environments were being automatically upgraded overnight to a Windows Server version for which they didn't even have a license. Microsoft recommends pausing Windows feature updates using Intune Windows Update client policies until the fix rolls out to all desktop devices affected by this issue. While the issue has since been mitigated, Microsoft has yet to share how Windows admins can roll back the automatic upgrades besides restoring systems from backups. Microsoft also resolved an issue where admins saw a prompt to upgrade to Windows Server 2025 on the Windows Update page. Microsoft is working to fix an ongoing issue causing some users' Windows devices to be offered Windows 11 upgrades despite Intune policies preventing them. The company also warned that users must manually revert systems that were mistakenly upgraded to Windows 11 because of this ongoing issue. In November 2024, Microsoft confirmed that some Windows Server 2019 and Windows Server 2022 devices were upgraded to Windows Server 2025 without warning. Although Microsoft has yet to share more information on how widespread this issue is, the incident has been tagged as an advisory, which implies a service issue that is limited in scope or impact. This isn't the first time Windows systems have been unexpectedly upgraded without the users' express consent. Redmond added earlier today in an update to the Microsoft 365 admin center (IT10561350) that a targeted code fix is now being deployed to prevent additional impact on other systems.
