The initial announcement, written by Windows Servicing and Delivery Principal Product Manager Jason Leznek, spends most of its time encouraging users and businesses to upgrade to Windows 11 rather than staying on 10, either by updating their current computers, upgrading to new PCs or transitioning to a Windows 365 cloud-based PC instead.

The company told us that "pricing will be provided at a later date," but for the Windows 7 version of the ESU program, Microsoft upped the cost of the program each year to encourage people to upgrade to a newer Windows version before they absolutely had to; the cost was also per-seat, so what you paid was proportional to the number of PCs you needed updates for.

Windows 10 has mostly been in a security-updates-only maintenance mode since the 22H2 update came out late last year, but Microsoft did "revisit" the operating system last month to add the Copilot generative AI assistant and a handful of other tweaks.

For businesses, educational institutions, or governments, the point of the ESU program has always been to buy slow-moving IT shops extra time to learn about the new features in newer versions of Windows, to educate and inform users about the upgrade, and to test for incompatibilities with other mission-critical hardware and software.

Windows 11's new system requirements add an additional wrinkle, though—not every single Windows 10 PC in every single organization officially supports Windows 11, adding the time and cost of hardware replacement (or migrating to a cloud-based setup) to the time and cost of changing operating system versions.
