Error 0x80073712 in Windows Server 2008 R2 indicates corrupted component store files preventing updates. The most effective resolution involves running the System File Checker followed by the Deployment Image Servicing and Management tool to repair system integrity. This sequence ensures underlying file corruption is addressed before attempting complex image repairs, restoring the update mechanism without requiring manual registry edits or service interruptions.
Understanding Error 0x80073712
The error code 0x80073712 specifically maps toERROR_SXS_COMPONENT_STORE_CORRUPT. In the context of Windows Server 2008 R2, this means the Component Store (also known as the WinSxS folder) contains missing or damaged files that are required for installing updates. When the Windows Update agent attempts to apply a patch, it verifies the integrity of these base components. If a hash mismatch occurs or a critical file is absent, the installation halts with this specific error.
This issue often arises after an interrupted update process, sudden power loss during disk writes, or aggressive third-party antivirus software interfering with system file modifications. Unlike general update failures, this error points directly to the foundational storage of Windows binaries rather than network connectivity or driver conflicts. Addressing the component store corruption is therefore a prerequisite for any further troubleshooting steps.
Prerequisites and Preparation
Before initiating repair commands, ensure you have administrative privileges on the server. Open the Command Prompt by navigating to Start, typingcmd, right-clicking cmd.exe, and selecting Run as administrator. It is crucial to run these tools from an elevated prompt; standard user permissions will result in access denied errors when modifying system-critical directories.
Additionally, disconnect any non-essential external peripherals. While rare, USB devices can sometimes interfere with low-level disk operations during file verification processes. Ensure the server has sufficient free disk space on the C: drive, as the DISM operation requires temporary workspace to download and replace corrupted manifest files. If the server is part of a domain, verify that no Group Policy Objects are actively blocking local command execution via restricted scripts.
Step 1: Run System File Checker
The first line of defense against component store issues is the System File Checker utility. This tool scans protected system files and replaces incorrect versions with correct Microsoft versions. Although some guides suggest skipping this step in favor of more aggressive measures, SFC provides a quick validation of core OS files. Type the following command into the elevated Command Prompt and press Enter:sfc /scannowStep 2: Repair Component Store with DISM
If SFC fails to resolve the issue or reports that it cannot fix some files, the Deployment Image Servicing and Management (DISM) tool is required. DISM operates at a deeper level than SFC, capable of repairing the entire Windows image including the component store. This is the definitive fix for error 0x80073712. Run the following command in the same elevated Command Prompt:dism /online /cleanup-image /restorehealth/source parameter pointing to a mounted ISO of the Windows Server 2008 R2 installation media.

Step 3: Verify and Install Updates
Once DISM completes successfully, runsfc /scannow one more time. The second pass should now find no violations, as the underlying component store has been repaired. If both tools report success, clear the Windows Update cache to ensure the server fetches fresh metadata. Stop the wuauserv service, rename the C:\Windows\SoftwareDistribution folder to SoftwareDistribution.old, and restart the service.
Finally, navigate to Control Panel > Windows Update and click Check for updates. The previously failing update should now install correctly.

Frequently Asked Questions
Can I ignore error 0x80073712?
No, ignoring this error will prevent all future security patches and feature updates from installing. Leaving the component store corrupted can eventually lead to system instability or failure to boot if critical system files become inaccessible over time.Does restarting the server fix this error?
A simple restart rarely fixes component store corruption because the damaged files remain on the disk. You must actively repair the files using SFC or DISM tools to restore integrity before a restart can finalize the changes.What if DISM fails with error 0x800f081f?
Error 0x800f081f typically means DISM cannot find the needed files in Windows Update. In this case, you must provide a local source by specifying the/source flag in the DISM command, pointing to the Sources\Sxs folder on your Windows Server 2008 R2 installation media.
