KB3033929 Does Not Install - Multi Boot Win7 / Linux Desktop

I need a resolution to this problem. It's been 2 weeks since Microsoft broke my Win 7 system. PLEASE fix or remove the patch, KB3033929, that is causing windows 7 to fail when updating.



Thank you for posting your query on Microsoft Community forum.

Microsoft has released a security advisory (KB3033929) for IT professionals about SHA-2 code signing support. The security advisory announces the availability of a security update and contains additional security-related information.

Some users cannot install this security update if their computers meet the following conditions:

  • Have a multiple-boot configuration of Windows and various distributions of Linux
  • Use a non-Windows boot loader
  • Have Windows and Linux installed on separate drives
We have been able to verify that systems that have the Windows boot loader enabled as the primary loader are successfully able to install this update and that systems that have a non-Windows boot loader specified as the primary boot loader cannot install the update, even if the user uses that loader to select Windows.

You may refer to the articles mentioned below and see if it helps you to fix the issue.

Microsoft Security Advisory 3033929

Microsoft security advisory: Availability of SHA-2 code signing support for Windows 7 and Windows Server 2008 R2: March 10, 2015
