Message Queuing (MSMQ) is a Microsoft technology that lets applications communicate asynchronously by sending messages to queues, enabling them to run at different times and even when systems or networks are temporarily offline. Microsoft's December 2025 security update disrupted Message Queuing functionality on Windows 10 and Windows Server systems, causing enterprise applications and IIS sites to fail. Users may receive the error message: Insufficient resources to perform operation (0x80004005).

Installing a new .NET version does not automatically uninstall older versions, meaning outdated End of Life runtimes can remain on systems indefinitely.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 This article explains how to inventory, assess dependencies, and safely remove outdated .NET Framework installations from Windows systems.
