A Slovak security firm named Acros Security has launched a service called 0patch, which focuses on safeguarding aging software, particularly Windows Server operating systems. Microsoft has officially discontinued support for these older versions, leaving them vulnerable to security threats. 0patch's service provides micro-patches to address vulnerabilities in these unsupported versions, including a critical remote code execution flaw in the Windows DNS Server service, as disclosed by Microsoft in August 2026.
By delivering these micro-patches while the operating system is running, Acros Security's solution allows organizations to maintain security without requiring a reboot or traditional software update installation. This approach is distinct from the regular Windows Update method. The new patches target Windows Server 2008 R2, Windows Server 2012, and Windows Server 2012 R2, which share core codebases with Windows 7, Windows 8, and Windows 8.1.
Acros Security plans to expand its support to cover more unsupported Windows releases in the near future, including Windows 10 version 22H2, which is scheduled for enrollment in the first year of Extended Security Updates (ESU) in October 2026.
