- Enterprise readiness for Windows 11 improves but still uneven, says new report
- Health care and financial sectors delay when upgrading outdated hardware
- Migration is slowest in America despite most units being upgraded ready
Millions of business units are still running Windows 10, even when Microsoft’s time limit to end support for us.
According to Controlup’s latest Windows 11 emergency report, half of all business-controlled Windows devices have not yet changed.
This number reflects progress from last year, as over 80% of the corporate machines were still on Windows 10, but with support ended on October 14, 2025, time is running out of organizations still lagging behind.
Wide variation across industries
“While the 50% mark is an important milestone, it’s not time to relax,” said Marcel Calef, Americas Field CTO at Controlup. “Many companies are still facing hardware and planning challenges.”
The report analyzed over a million units and found broad variation across industries.
Education and tech lead, with over 70% of the systems upgraded. Healthcare and Finance Trail far behind, with fewer than half of their devices running Windows 11. Some health units are simply too old, with 19%that needs replacement before an upgrade is possible.
Regional trends show that America is the slowest to move on. Only 43% of business units upgraded compared to 70% in Europe.
In particular, most of the non-upgraded machines in America are technically able to run Windows 11, but the contact has not been made.
Larger organizations are also behind. Those who manage more than 10,000 Windows devices have completed only 42% of migration. Complex environments and aging infrastructure slow down progress.
If your business is still using Windows 10 it’s time to intervene. Start by checking which devices meet Windows 11’s requirements, such as TPM 2.0 and Secure Boot. Replace what cannot be upgraded and planned updates for the rest. Prioritize units at high risk, back up data and keep systems patched during the transition.
If upgrading is not possible, you must reduce the risk of limiting access to sensitive systems, enabling built -in protection and isolating outdated devices. Make sure all updates are current and that you run the best antivirus software and the best malware protection.
Microsoft is fully aware that the deadline is bad news for many companies and offers paid support through its extended security updates (ESU) program, open to individuals and organizations. Of course, it’s not cheap.
Third -party provider 0Patch also plans to provide security fixes for at least five years after Microsoft ends support.
