Preparation for the company for Windows 11 improves but always uneven, says a new report
The health and finance sectors are lagging behind in the upgrading of obsolete equipment
Migration is the slowest in the Americas despite most of the apparatus ready for upgrading

Millions of corporate aircraft are still running Windows 10, even as Microsoft’s deadline to end the management of operating system approaches.

According to the latest Windows 11 Controlup preparation report, half of all the Windows devices managed by the company have not yet made the change.

This number reflects progress compared to last year, when more than 80% of corporate machines were still on Windows 10, but with the support ending on October 14, 2025, the weather is running out for organizations that are still lagging behind.

Broad variation between industries

“Although the 50% completion brand is an important step, there is no time to relax,” said Marcel Calef, CTO Americas Field in Controlup. “Many companies are always faced with material challenges and planning.”

The report analyzed more than a million aircraft and found large -scale variations between industries.

Education and technology open the way, with more than 70% of the upgraded systems. Health care and finance take place far behind, with less than half of their devices running Windows 11. Some health devices are simply too old, 19% needing replacement before an upgrade is possible.

Regional trends show that the Americas are the slowest to move forward. Only 43% of corporate devices are upgraded, compared to 70% in Europe.

In particular, most of the machines not increased by the Americas are technically capable of executing Windows 11, but the switch has not been made.

Large organizations are also late. Those who managed more than 10,000 Windows aircraft carried out only 42% of migration. Complex environments and aging infrastructure slow down progress.

If your business still uses Windows 10, it’s time to act. Start by checking which devices meet Windows 11 requirements, such as TPM 2.0 and secure start -up. Replace what cannot be upgraded and plan gradual updates for the rest. Prioritize high -risk devices, save data and keep the corrected systems during the transition.

If the upgrade is not possible, reduce the risk by limiting access to sensitive systems, by allowing integrated protections and isolating obsolete devices. Make sure that all updates are up to date and that you run the best antivirus software and the best protection against malware.

Microsoft is perfectly aware that the deadline is bad news for many companies and offers support paid through its extensive security update program (ESU), open to individuals and organizations. It’s not cheap of course.

The Third Party 0patch supplier also plans to provide security fixes for at least five years after the Microsoft support ended.
