Windows couldn't complete the requested changes. Error 0x800F0907

 In this post, I describe how to fix the error:

"Windows couldn't complete the requested changes.

Because of network policy settings, Windows couldn't connect to the Internet to download files that are required to complete the requested changes. Contact your network administrator for more information.

Error code: 0x800F0907"

Cause

This error can occur when you try to install a Windows feature e.g. .NET Extensibility 3.5 in Internet Information Services:

And the policy 'Specify settings for optional component installation and component repair' has 'Never attempt to download payload from Windows Update' checked:

Resolution 1

To resolve the issue, go to the policy in Computer Configuration > Administrative Templates > System, uncheck the 'Never attempt to download payload from Windows Update' checkbox.

Ensure the policy is updated on the computer e.g. gpupdate.

The Windows Features installer can now proceed by letting Windows Update download the files:

Resolution 2

Alternatively, use DISM to install the feature and specify an alternative source to the Windows installation media e.g.

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs
