Microsoft Releases KB2993651 Update To Fix Botched Update For MS14-045


Microsoft have issued a revised update for MS 14-045 with KB2993651 which replaces KB2982791. This is being rolled out by Windows Automatic Update. Please see my previous post about this Problems with Windows updates August 2014 KB2982791 KB2970228 KB2975719 KB2975331

However reading the instructions, Microsoft recommends all users to uninstall KB2982791 if they haven’t already done so and install this update.

My gut feeling and advice is to hold off on this update, for now, which also has potential unwanted features, until we see some feedback from other users in the field as to how it actually affects users in the real world. I would be extremely concerned if windows and programs running suddenly become invisible or hide behind other windows and you can’t effective work.

Edit: we are already seeing some reports on forums of blue screens, Kernel crashes and failure to install this patch on both Windows 7 and 8 computers, with windows automatically reverting to the previous configuration state on a forced reboot

Known Issue 2

After you install this update, the z-order of the windows is changed. (The z-order calls the SetWindowPos function together with the HWND_TOP parameter.) Therefore, the windows of certain applications may become invisible or may be incorrectly displayed behind other windows.

We are currently working on a resolution for this issue.

This issue also occurs after you install the following updates:

  • 2965768 Stop error 0x3B when an application changes the z-order of a window in Windows 7 SP1 and Windows Server 2008 R2 SP1
  • 2970228 Update to support the new currency symbol for the Russian ruble in Windows
  • 2973201 MS14-039: Description of the security update for Windows on-screen keyboard: July 8, 2014
  • 2975719 August 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2
