Windows 11 KB5079391 Update Pulled: Resolving 0x80073712 Errors

The withdrawal of the KB5079391 non-security preview update marks a significant disruption for early adopters of Windows 11 version 24H2. According to BleepingComputer, Microsoft took the step of removing the update from Windows Update, Microsoft Update, and the Microsoft Update Catalog after acknowledging reports of persistent installation failures. These failures are primarily characterized by the error code 0x80073712, which typically indicates that a file required by Windows Update is damaged or missing.

While this release was an optional “C-update” intended to test new features and fixes ahead of the February Patch Tuesday, its failure has caused friction for IT departments. For organizations that leverage these preview windows to validate system stability, the Microsoft KB5079391 withdrawal impact necessitates a pause in deployment scripts and a review of update health dashboards.

Technical Analysis of the 0x80073712 Error

The 0x80073712 error (ERROR_SXS_COMPONENT_STORE_CORRUPT) is a well-known issue within the Windows Servicing Stack. It suggests that the Component-Based Servicing (CBS) store has encountered a state where it can no longer verify the integrity of the files it is attempting to update. In the context of KB5079391, the error appears to trigger during the final stages of the installation process.

Administrators tasked with Windows 11 version 24H2 update troubleshooting should note that while this update contains no security-related CVE fixes, the underlying cause of the installation failure could potentially mask other issues within the component store. Because this update was not a mandatory security release, it did not receive a CVSS score, but the operational impact for SOC and IT operations teams is notable due to the noise generated in SIEM environments by failed update telemetry.

Troubleshooting Windows 11 version 24H2 update issues

For systems that have already attempted and failed the installation, the update may remain in a “pending” or “failed” state within the Windows Update history. Security professionals often look for ways to clear these states to ensure subsequent, stable updates—such as the upcoming February security releases—can be applied without interference. Understanding how to fix Windows 11 KB5079391 install error 0x80073712 involves verifying the integrity of the local image using tools like Deployment Image Servicing and Management (DISM) and the System File Checker (SFC).

Impact on Enterprise Patch Management

The sudden removal of an update package can complicate automated patch management workflows. If an EDR or patch management solution was configured to automatically pull and push “preview” updates to a subset of machines, the withdrawal might result in “missing package” errors or sync failures.

Microsoft’s decision to pull the update entirely, rather than just issuing a workaround, suggests that the root cause may require a re-engineered update package. This highlights the importance of maintaining a Zero Trust approach to software updates: even updates sourced directly from the official vendor should be staged in limited “rings” before broad internal distribution.

Mitigation and Recommendations

Microsoft is currently investigating the issue and plans to provide an update once more information is available. In the interim, the following steps are recommended:

• Cease Deployment: If you use Windows Server Update Services (WSUS) or similar tools, ensure that KB5079391 is declined or removed from active deployment groups.
• Monitor System Health: Use SIEM logs to identify hosts reporting the 0x80073712 error code to determine the scale of the failure within your environment.
• Wait for the Revised Release: Since this is a non-security update, there is no immediate risk in skipping it. The fixes contained within KB5079391 will likely be rolled into the mandatory February 2025 security update.
• Component Store Repair: For systems experiencing persistent update issues after the failed installation, run dism /online /cleanup-image /restorehealth followed by sfc /scannow to ensure the integrity of the Windows image.

By adhering to these practices, organizations can minimize the operational overhead caused by buggy preview releases and maintain a stable environment for their users.
