Microsoft has officially ceased all support for Windows Server 2008 as of January 13, 2026, including paid extended security updates. This end-of-life scenario poses significant security risks for organizations still using the outdated operating system, making them vulnerable to cyberattacks. The transition away from Windows Server 2008 requires careful planning, as many organizations face challenges in migrating legacy applications to modern systems. The lack of ongoing patches means that any new vulnerabilities will remain unaddressed, potentially leading to data breaches and compliance failures, particularly in regulated sectors like healthcare and finance. Microsoft has encouraged migration to Azure, offering incentives for early adopters, but the transition can be complex and costly. The end of support also affects global supply chains and compatibility with newer software applications. Organizations are advised to conduct audits of their software portfolios and consider hybrid environments to enhance flexibility and security.

Microsoft concluded all support for Windows Vista and Server 2008 as of January 13, 2026. Most customers lost support in January 2020, but Extended Security Updates were available until January 2023 for most users and until January 2024 for Azure customers. Free security updates, non-security updates, and support options are no longer accessible for the retired codebase. Organizations are encouraged to migrate to Azure for additional security updates. Windows Server 2012 will also reach the end of its ESU on October 13, 2026.

The Collections tool in Microsoft Edge is being retired, and users will soon be unable to add new items to it. They are advised to export their saved content or transfer pages to Favorites before the feature is removed. Transferring to Favorites will result in the loss of additional content like images and notes, while exporting will preserve content in a CSV file but will not keep it within the browser. Collections has not gained significant traction among users, leading to its phased-out status. Additionally, the Edge Sidebar app list is also being retired, raising concerns about the future of the entire Sidebar feature as Microsoft aims to simplify Edge and promote Copilot.

Microsoft will conclude support for its Windows 11 SE operating system, designed for K–8 classrooms, by the end of 2026. The final version will be 24H2, and full support, including security patches, will end on October 13, 2026. Schools using these devices will face challenges as they will no longer receive security updates, raising concerns about student data privacy. Microsoft is advising educational institutions to consider hardware that supports standard versions of Windows 11. This shift creates budgetary concerns for schools that invested in the SE ecosystem, as they will need to secure funds for upgrades or replacements.

Microsoft has announced the phased discontinuation of the RC4 encryption cipher, with full implementation expected by mid-2026. RC4, created in 1987, has been increasingly recognized as a vulnerability, exploited in various high-profile cyberattacks. Microsoft plans to disable RC4 by default in Windows Kerberos authentication, encouraging organizations to transition to more secure alternatives like AES-256. This decision follows years of warnings from the cybersecurity community and aims to eliminate long-standing cryptographic weaknesses. The transition will require organizations to audit and upgrade their infrastructures, as many legacy applications still depend on RC4. Disabling RC4 is expected to reduce the success rates of attacks exploiting weak encryption. Microsoft has introduced tools to help administrators identify hidden RC4 usage. The change reflects a commitment to zero-trust architectures and aligns with recommendations from organizations like NIST. Experts recommend a multi-step approach for organizations to navigate this transition effectively.
