Windows Update Client for Windows 8.1: June 2015

An update to the Windows Update Client is available. This update has prerequisites.

Fixes that are included in this update

  • A change is made on the log level for %windir%\WindowsUpdate.log to reduce the frequency of certain events from exhausting log space.
  • Fixes an issue for managed computers in which managed computers have to update drivers as a set. Driver sets are not processed by Windows Update during shutdown, and are still available to be installed after you restart the computer.
  • Fixes an issue in which the files of an update may not be found by Windows Update (0x80070002) if the download operation spans multiple sessions.
  • General improvements are made to support upgrades to Windows 10. 
  • This update installs a new Group Policy object that enables you to block upgrades to the latest version of Windows through Windows Update.

    Microsoft is making Windows 10 available for free for one year from the date of availability to Windows 7 and Windows 8.1 customers for non-Enterprise editions. If you have Windows 7 or Windows 8.1 Pro deployed in your organization, Windows 10 will be offered to you. Computers that have this Group Policy object enabled will never detect, download, or install an upgrade to the latest version of Windows. 

    You can configure this Group Policy object by using Group Policy (if the update is installed and if you use the updated WindowsUpdate.admx file by copying the file from where the editing policy is located). You can also do this by going to Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Update, double-clicking Turn off the upgrade to the latest version of Windows through Windows Update, and then clicking Enabled.

    Policy path Computer Configuration / Administrative Templates / Windows Components / Windows Update

    Policy setting Turn off the upgrade to the latest version of Windows through Windows Update (enabled or disabled)

    To suppress this offer through the registry, set the following registry key:
    HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
    DWORD: DisableOSUpgrade = 1
