Specify source service for specific classes of Windows Updates breaks installation of .net 3.5, languages, optional features...

Daniel 21 Reputation points


Since configuring the new Windows Update Policy setting "Specify source service for specific classes of Windows Updates" I am experiencing issues installing certain windows features.

.net 3.5 framework fails with 0x800f0950
languages fail with 0x800f0954

It can temporarily be solved by changing the data of SetPolicyDrivenUpdateSourceForQualityUpdates from 1 to 0, basically telling the client to download and install quality updates from microsoft update instead of WSUS, which is obviously not what I want.

So it looks like pointing SetPolicyDrivenUpdateSourceForQualityUpdates to WSUS, causes the setting Specify settings for optional component installation and component repair to no longer work.

Can this be fixed somehow?

    Do you have "Do not allow update deferral policies to cause scans against Windows Update" enabled? If so, set it to Not Configured.

    This is where I got the info from. I haven't read it all, but it was released yesterday by Aria.

    Hello Daniel,

    Can you check the next thread, it may give you the solution and explanation of the error for .NET error related to the Developer Mode: https://social.msdn.microsoft.com/Forums/en-US/44f648dd-e1cd-42a9-91de-29d3e654459d/activating-developer-mode-error-code-0x800f0950?forum=windowsgeneraldevelopmentissues

    All in all I would suggest for both issues to enable the next policy as it would be required for certain updates and downloads not supported by WSUS:

    Enable download of “Optional features” directly from Windows Update:

    Open the group policy editor on your domain
    Create a new GPO, or modify an existing one. Make sure it applies to the computers you’d like
    Navigate to “Computer Configuration”, “Policies”, “Administrative Templates”, and then “System”.
    Double click or open “Specify settings for optional component installation and component repair”
    Make sure “Never attempt to download payload from Windows Update” is NOT checked
    Make sure “Download repair content and optional features directly from Windows Update instead of Windows Server Update Services (WSUS)” IS checked.
    Wait for your GPO to update, or run “gpupdate /force” on the workstations.

    Same problem here, highly disappointed the issue has not been acknowledged by Microsoft...

    Are there any updates on how to solve this issue? Is this going to be fixed with UUP?
