KB317694 breaks PowerShell, fixed in next Windows Update, “due 8/30/2016”

Earlier this week Microsoft pushed out update KB317694 as a patch to those systems with the Windows 10 Anniversary Update installed. Such updates are usually meant to increase the stability of Windows, but unfortunately, Microsoft wants you to know that the patch has broken Windows PowerShell.

The update, apparently, has a missing  .MOF file in the build package. Additionally, there is missing binary in the build package which breaks PowerShell implicit remoting.  Microsoft is providing the following workaround to these issues:

  1. From elevated PowerShell prompt type:         wusa /uninstall/ kb:3176934
  2. If using WSUS, do not approve the update. Otherwise, Use Group Policy to set the ‘Configure Automatic Updates’ to ‘2 – Notify for download and notify for install’ as described in this Microsoft Support article.

The MSDN blog post notes that a fix is coming, and apparently reveals that the next Windows Update will arrive next week, on August 30th.

Stay tuned to WinBeta for updates, as once Microsoft drops the next Windows Update to correct the issue next week we will be here to cover it for you. Until then, be sure to follow us on Twitter to make sure that you’re up to date on all your Windows 10 news and information.
