Microsoft is offering Extended Security Updates (ESUs) for Windows Server 2016, which will provide critical security patches until January 2030, after the end of extended support on January 12, 2027. Organizations can enroll their Windows Server 2016 instances via Azure Arc to receive these updates without migrating to Azure. The ESUs are available through a pay-as-you-go pricing model, allowing flexibility for on-premises servers and other cloud platforms. By using Azure Arc, organizations gain access to Azure management tools for improved visibility and compliance. IT administrators should connect eligible systems to Azure Arc to manage ESU enrollment and compliance effectively. ESUs are intended as a temporary solution while businesses modernize applications and plan migrations to supported platforms.

Windows operating systems have hidden functionalities and privacy enhancements introduced through regular updates, which are crucial for maintaining system security. Neglecting updates leaves known vulnerabilities open to exploitation by malicious actors, as Microsoft typically addresses security flaws only after they are identified. Windows Update is the primary mechanism for addressing these vulnerabilities. Unpatched systems become targets for cyber threats, leading to severe consequences such as remote code execution, privilege escalation, ransomware attacks, and boot-level compromises. The PrintNightmare vulnerability (CVE-2021-34527) was acknowledged by Microsoft after active exploitation was detected, leading to the release of patches. The WannaCry cyberattack in May 2017 affected over 300,000 computers due to an unpatched SMB flaw, highlighting the risks of outdated systems. Timely updates can prevent vulnerabilities that may lead to ransomware, credential theft, and other compromises. Users are advised to install updates promptly and avoid connecting unsupported versions to the internet.

Microsoft has extended its Extended Security Updates (ESU) program for Windows 10 consumers until October 12, 2027, providing critical security updates for eligible systems. Windows 10 remains functional, but no new features will be introduced, and users must ensure their devices are enrolled in the ESU program to receive updates. Users are advised to check their computer's compatibility with Windows 11 and consider upgrading, as it is available as a free upgrade for eligible machines. If a computer does not meet the requirements for Windows 11, the ESU extension allows additional time to plan for replacement. Users should keep their internet security software and applications updated and maintain backups of important data.

A study by Lansweeper found that Windows 10 PCs have an average of 1,903 active security vulnerabilities, while Windows 11 systems have only 652 vulnerabilities. As of June 2026, nearly 20% of Windows PCs in the U.S. are still using Windows 10, despite Microsoft ceasing regular updates for it. Users can enroll in the Extended Security Updates (ESU) program for continued security updates until October 12, 2027. Security experts have urged users to upgrade to Windows 11 due to increasing vulnerabilities in Windows 10, while some data privacy experts recommend staying with Windows 10 for as long as possible.
