Earlier today, Microsoft released Windows 10 build 17134.191 for those on the Windows 10 April 2018 Update, or version 1803. Despite Patch Tuesday being two weeks ago and the company having released a round of updates last week, Microsoft is also releasing patches for some older versions of Windows 10.
If your PC somehow hasn"t been upgraded to version 1803 and you"re still on the Windows 10 Fall Creators Update, or version 1709, you"ll get KB4338817, and that brings the build number to 16299.579. You can manually download it here, and it contains the following fixes:
Addresses an issue that causes devices within Active Directory or Hybrid AADJ++ domains to unexpectedly unenroll from Microsoft Intune or third-party MDM services after installing provisioning package updates (PPKG). This issue occurs on devices that are subject to the “Auto MDM Enrollment with AAD Token” Group Policy. If you ran the script “Disable-AutoEnrollMDMCSE.PS1” as a workaround for this issue, run “Enable-AutoEnrollMDMCSE.PS1” from a PowerShell window running in Administrator mode after installing this update.
Inserts a CR before LF if there was none.
