Add Microsoft Feature to Windows on Xavier-Issued PC

Adding a Windows Feature or Language (including the additional items such as typing) results in a failure, sometimes with error code 0x800F0954 and sometimes as simply a failure to download. Temporarily disabling the use of the Xavier internal Windows Update server will allow the installation.

Issue

Adding a Windows Feature, such as .NET 3.5 or an additional language pack, fails. The download does not occur and thus the installation gives an error that it cannot download (error code 0x800F0954 for example).

Cause

Xavier-issued Windows machines are configured to use an update server internal to Xavier. We do not host the optional features and languages. The error is expected when encountering this situation. It can be corrected through following steps.

Prerequisite

The operator will need administrator level access to accomplish this task.
