Windows moves on from Windows 10, and thousands of users in Spain still haven’t made the leap.
The end of official support for Windows 10 in October 2025 marked a turning point for cybersecurity. However, a recent study by Kaspersky, based on data collected through the Kaspersky Security Network (KSN), confirms that a significant portion of users in Spain continue using older versions of the operating system, increasing their exposure to cyber threats.
According to the analyzed data, only 37% of Spanish users have migrated to Windows 11, while more than 50% are still operating on Windows 10, despite it no longer receiving security patches. Even more concerning is that nearly 5% are still using Windows 7, a system for which Microsoft stopped providing updates back in 2020.

Unsupported software: a critical
vulnerability for the business environment
For organizations—especially SMEs—this lack of updates represents a direct risk. Without patches or security improvements, outdated systems become an open door for malware attacks, ransomware, and data theft.
Kaspersky’s data shows that:
Kaspersky’s data shows that:
- 53% of corporate devices in Spain still use Windows 10.
- Among SMEs, the figure is 50.4%.
- In large companies, the percentage is slightly above the average.
- 4% of SMEs and 2.5% of large corporations continue using Windows 7.
The rise of AI-powered cyberattacks
is worsening the landscape
The report also highlights that current threats are evolving rapidly, driven in part by attackers’ use of Artificial Intelligence.
According to the study ‘Cyber Defense and AI: Are You Ready to Protect Your Organization?’ conducted by Kaspersky:
AI is enabling the automation of attacks, enhancing evasion techniques, and creating highly personalized phishing campaigns, making it even more difficult for organizations with outdated systems to defend themselves.
- 71% of Spanish companies consider AI-powered attacks a serious threat.
- 42% report that recent cyberattacks they experienced involved AI in their execution.

More organized criminals and
more sophisticated attacks
The company itself notes, through specialists like Oleg Gorobets, that cybercriminals have improved their organization and collaboration. They now share tools, develop more advanced strategies, and enable less experienced attackers to use complex techniques.
This means that a company with outdated systems doesn’t need to be a ‘high-value’ target to suffer an attack: being vulnerable is enough.
What should a company do?
- Update or migrate to Windows versions with active support.
- Implement multilayer security solutions capable of detecting advanced threats.
- Strengthen preventive security rather than relying solely on reactive measures.
- Monitor systems using threat intelligence.
- Incorporate tools based on defensive AI to counter automated attacks.
In conclusion
The current situation confirms that outdated systems remain one of the biggest cybersecurity challenges in Spain, especially for SMEs that rely on older devices for their daily operations.
With Windows 10 officially out of support and the constant rise of intelligent threats, postponing updates is no longer an option: it is a decision that can compromise security, data, and business continuity.
