Recent Microsoft Entra and Windows updates introduce multiple changes across authentication, identity management, and access control. The updates include an option to replace the legacy EdgeHTML WebView with the Chromium-based WebView2 for Entra ID authentication flows, improved identity constructs for AI agents, public preview support for synced passkeys, and expanded self-service account recovery. Additional changes cover jailbreak detection in Microsoft Authenticator, enforcement of a stricter Content Security Policy for browser-based sign-ins, updates to session revocation behavior, and new capabilities in Entra ID Governance, External ID, and Global Secure Access.

Installing a new .NET version does not automatically uninstall older versions, meaning outdated End of Life runtimes can remain on systems indefinitely. These unsupported versions pose serious security risks as they no longer receive patches for newly discovered vulnerabilities. Microsoft ceased support for .NET Framework 4.5.2, 4.6, and 4.6.1 on April 26, 2022, leaving systems running these versions exposed to exploitation and compliance violations. Administrators must actively identify applications using End-of-Life runtimes and coordinate with development teams to migrate them to supported versions. This article explains how to inventory, assess dependencies, and safely remove outdated .NET Framework installations from Windows systems.
