Today, October 14, support for Windows 10 ends, according to Microsoft's official announcement, with hundreds of millions of devices entering the "End of Support" phase.
The cessation of updates simply means the cessation of security support. This means that any security vulnerabilities discovered after that date will not be patched by Microsoft, leaving the system vulnerable to zero-day ransomware attacks. These attacks are dangerous because they exploit an unknown security loophole, and there is no preparedness to prevent them.
While Microsoft has introduced a fee-based Extended Security Updates (ESU) option for organizations that wish to continue temporarily, it has emphasized that reliance on pirated and outdated versions, along with a lack of awareness of digital security, could create a significant gap in digital protection and make these devices an ideal target for attacks.
The future challenges facing users of this system are significant. Outdated systems within corporate networks could be used as a breach point for sensitive data or entire infrastructure. Continued operation of an unsupported system in the healthcare, banking, or sensitive data sectors could constitute a violation of security standards.
Because support for Windows 10 boot files has been discontinued, even the most powerful antivirus software cannot fix errors in the system kernel or files, according to cybersecurity expert Dima Mohammed.
Despite the four years since the launch of Windows 11, a large number of users around the world still rely on Windows 10. Data from StatCounter, a website specializing in monitoring internet traffic and the share of operating systems and browsers, shows that this operating system will still power approximately 40% of desktop computers globally as of September 2025.
Specialized reports indicate that many of these devices, particularly in developing countries, do not meet the strict hardware requirements of Windows 11, such as the TPM 2.0 chip and modern processors, making its security system vulnerable.
Microsoft defended its decision by explaining that "each operating system has a specific lifecycle, with a maximum support lifetime of ten years." She added that modern security requirements require a new architecture that Windows 10 does not provide.
In other words, the system is simply no longer capable of keeping pace with the rise of modern cyber threats and attacks, and it cannot be radically upgraded without a complete redesign, which Microsoft announced with the release of Windows 11.
The Windows 10 era is ending, and millions of devices are at risk after security updates were halted.
