Overview
- KB5068781 is the first Extended Security Update for Windows 10 released after official support ended in October 2025.
- Microsoft confirms the installation issue occurs only on devices using Windows Subscription Activation through the Microsoft 365 Admin Center.
- Administrators report that installations appear to proceed, then roll back after reboot, and some devices do not see the update at all.
- There is no published workaround or timeline for a fix as Microsoft investigates, leaving impacted machines without November security patches.
- Home users and systems with classic or manual ESU activation generally install the update successfully according to current reports.
