As Microsoft prepares to end support for Windows 10 on October 14, 2025, both individual users and organizations are confronting a critical choice: migrate to Windows 11 or continue running an unsupported operating system. Once the deadline passes, devices will no longer receive free security updates, leaving them increasingly exposed to cyberattacks—a serious concern given Windows 10’s vast global presence, with over 400 million active installations.
For IT managers and cybersecurity professionals, this transition goes beyond a routine upgrade; it represents a strategic decision affecting operational stability, regulatory compliance, and budget planning.
The move to Windows 11 also brings stricter hardware requirements, including TPM 2.0 and Secure Boot, which render many older PCs incompatible. Those unable or unwilling to upgrade must carefully weigh the consequences, including heightened susceptibility to malware, zero-day vulnerabilities, and software incompatibilities.
Experts caution that unpatched systems can quickly become high-risk targets, echoing incidents like the 2017 WannaCry ransomware outbreak that exploited vulnerabilities in unsupported Windows environments.
Understanding the Security Implications:
Recent research underscores the growing dangers of remaining on Windows 10. A report by Sikich indicates that organizations continuing with the legacy OS face increased chances of data breaches, regulatory violations, and costly operational downtime.
Windows Central similarly notes that cybercriminals are likely to prioritize unsupported systems as easy targets, heightening the urgency for businesses to plan their upgrade paths proactively.
What happens after October 14, 2025:
Windows 10 PCs will still work: The operating system itself will continue to operate.
No more security updates: Microsoft will stop providing security fixes, which is a significant risk.
No new features: You won’t receive any new software or feature updates.
No technical support: Microsoft will no longer provide technical assistance for Windows 10.
What to do to stay secure:
Upgrade to Windows 11: This is the best and most recommended option for a modern, secure computing experience.
Enroll in the Extended Security Updates (ESU) program: This paid program provides security updates for a limited time (up to three years for Microsoft 365 apps, extending until October 2028 for Windows 10).
Use Microsoft 365 Apps: If you have a Microsoft 365 subscription, your applications will continue to function on Windows 10 for a period even after the OS support ends.
