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Installing a new .NET version does not automatically uninstall older versions, meaning outdated End of Life runtimes can remain on systems indefinitely.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 This article explains how to inventory, assess dependencies, and safely remove outdated .NET Framework installations from Windows systems.

Windows 10 devices enrolled in Extended Security Updates may experience installation failures when attempting to install the November 2025 security update (KB5068781). There were some problems installing updates, but we'll try again later. "Error encountered: If you keep seeing this and want to search the web or contact support for information, this may help: (0x800f0922)." The issue affects a specific subset of commercial customers using cloud-based licensing activation. This ESU issue appears to be unrelated to the error, 'We can't enroll you in Extended Security Updates right now,' because the enrollment error prevents access to ESU updates, while the current issue affects installation on devices that are already enrolled. Microsoft now released the KB5072653 update to fix the 0x800f0922 error.

Windows Server 2025 implements security hardening changes that block WSUS from distributing extended security updates (ESU) to end-of-life operating systems. The modifications affect Windows Server 2012 and 2012 R2 systems receiving ESU updates through WSUS, requiring administrators to implement workarounds or upgrade their infrastructure.
