About this tag
Office updates on WindowsForum.com cover the monthly Microsoft Office security releases for Microsoft 365 Apps and perpetual Office versions, including Office LTSC, Office 2021, Office 2024, and Office 2019. Discussions focus on patching vulnerabilities such as PowerPoint information disclosure flaws and Excel remote code execution issues, with an emphasis on deploying the August 2026 Office updates across managed channels. A recurring theme is that these fixes arrive through the Office update train, not Windows cumulative updates, and administrators must verify installed builds. The tag also addresses Microsoft 365 feature baseline changes for Windows 10, where Version 2608 marks the cutoff for new features while security updates continue through October 2028.
