Windows 10 refuses to die, and the security bill is coming due
Summary
Despite reaching its end of support in October 2025, a significant portion of Windows 10 machines remain unmigrated. This continued reliance on an unsupported operating system poses a substantial security risk, as these systems will no longer receive critical security patches.
IFF Assessment
Unsupported operating systems without security patches create significant vulnerabilities that attackers can exploit, increasing the risk of breaches and system compromise.
Defender Context
Organizations and individuals still running Windows 10 past its end-of-support date in October 2025 face elevated security risks. Defenders must prioritize migrating to supported operating systems or explore Extended Security Updates (ESUs) to mitigate potential vulnerabilities that will no longer be patched.
