Fix Error 0x80072f8f using Update KB3138612

Encountering error 0x80072f8f during Windows Update can be frustrating, especially if the update in question is KB3138612. 

This error code typically indicates an issue with corrupted system files or permission problems that prevent the update from installing successfully. 

While KB3138612 is no longer critical for most users due to the end of extended support for Windows 7 in January 2020, if you're still on Windows 7 and facing this error, here are some steps you can try to fix it.

Understanding the Error:

Error 0x80072f8f often points towards problems with the Windows Update service itself or corrupted system files that the update relies on. In some cases, permission issues might also hinder the update process.

What is KB3138612?

KB3138612 was a security update released in April 2016 for Windows 7 and Windows Server 2008 R2. 

While it addressed vulnerabilities, it's important to note that Microsoft no longer supports Windows 7, meaning you won't receive further security updates.

Upgrading to a supported operating system like Windows 10 or 11 is highly recommended for continued security and feature updates.

Fixing Error 0x80072f8f with KB3138612:

Here are some methods you can attempt to resolve the error and install KB3138612:

Run Windows Update Troubleshooter:

Open the Start menu and search for "troubleshoot."

Click on "Troubleshoot computer problems."

Under "System and Security," select "Fix problems with Windows Update."

Run the troubleshooter and follow the on-screen instructions. It might identify and fix the underlying issue causing the update failure.

Reset Windows Update Components:

This method involves stopping certain Windows Update services, deleting temporary update files, and then restarting the services. It can help clear corruption within the update process.

A detailed guide on resetting Windows Update components can be found on Microsoft's support website ([search microsoft reset windows update components ON support.microsoft.com]).

Run System File Checker (SFC) and Deployment Image Servicing and Management (DISM):

SFC scans and repairs corrupted system files, while DISM can repair the Windows image itself.

Open Command Prompt as administrator (search for "cmd," right-click and select "Run as administrator").

Type sfc /scannow and press Enter. Let the scan complete.

If SFC finds corrupted files but cannot repair them, type the following commands one by one, pressing Enter after each:

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /RestoreHealth

These DISM commands can take time to complete, so be patient. Restart your computer after SFC and DISM scans are finished.

Manually Download and Install KB3138612:

If the automatic update process fails persistently, you can download the standalone installer for KB3138612 from the Microsoft Update Catalog (https://www.catalog.update.microsoft.com/).

Make sure to download the version compatible with your system architecture (32-bit or 64-bit).

Run the downloaded installer and follow the on-screen instructions.

Important Considerations:

Limited Support for Windows 7: As mentioned earlier, Microsoft no longer offers extended support for Windows 7. 

This means you won't receive security updates, leaving your system vulnerable. Upgrading to a supported operating system is crucial for continued security.

Alternative Methods: If the above methods fail to resolve the error, consider seeking assistance from Microsoft support forums or professional IT help. 

However, their ability to provide a permanent fix might be limited due to the lack of official support for Windows 7.

While fixing error 0x80072f8f with update KB3138612 is possible using the methods mentioned above, it's important to remember the limitations of an unsupported operating system. 

Upgrading to a supported Windows version is the most secure option in the long run. If you must remain on Windows 7 for now, prioritize these fixes and exercise caution while using the internet due to the increased security risks.
