Microsoft has released a new update aimed at resolving issues affecting commercial customers enrolled in the Extended Security Updates (ESU) program for Windows 10. Many organizations reported error messages during the first Patch Tuesday after official support ended, raising concerns about the stability of the ESU rollout. The company is now offering a dedicated preparation package to ensure devices can continue receiving security patches as intended.
The New ESU Preparation Package
Microsoft delivered the fix through update KB5072653, described as the “Extended Security Updates (ESU) Licensing Preparation Package for Windows 10.” The company has not detailed the exact function of the package but stated that it must be installed before deploying the November 11 security update. Devices must also have the October 2025 security update installed prior to applying the preparation package.
The ESU program allows customers to receive security patches beyond Windows 10’s end of support. It is a paid service, though select users may avoid charges depending on their region or participation in certain Microsoft services.
Enrollment Challenges for Customers
Despite being announced more than a year ago, the ESU program has had a difficult launch. Some users experienced problems with the enrollment wizard, while others saw installation failures after activating devices through the Microsoft 365 admin center. The transition has been particularly frustrating for IT administrators, given the steep pricing: $61 per device for the first year, with the cost doubling annually.
Microsoft has not disclosed how many Windows 10 systems are still in use or how many customers are enrolled in the ESU program. However, the difficulties highlight the complexity of extending security support to such a large installed base.
Windows 11 Adoption Remains Slow
Market data underscores why so many customers remain on Windows 10. According to Statcounter, Windows 11 did not surpass Windows 10 in market share until June 2025. Even after the end of free support, Windows 10 still represented more than 40 percent of all Windows desktop installations. Hardware requirements for Windows 11 have been a major barrier, leaving many devices unable to upgrade.
As a result, the ESU program remains critical for organizations relying on older hardware. While the rollout has been uneven, Microsoft expects the system to operate correctly for all customers once the new preparation package is implemented.
Looking Ahead
The fix marks an important step in stabilizing the ESU offering and restoring confidence among customers who depend on Windows 10 for ongoing security. As organizations move through the transition period, proper installation of prerequisite updates will remain essential to avoiding disruptions.
