If you have a proxy server configured and you try to check for and download updates
through Windows Update on the Surface Hub, the download either doesn't start or
remains stuck at 1% progress. If you check for and download updates on a connection
that has a direct access to the Windows Update servers, this works without a problem.
This issue occurs if a proxy tries to do any of the following:
SSL inspection
Cache updates from Windows Update
Block support for partial file download (HTTP range headers)
Windows Update uses dynamically created temporary file names that differ for each
computer that downloads updates. This eliminates any benefit that might be gained
from caching. Windows Update also uses the Background Intelligent Transfer Service
(BITS) as a client, which can request partial files—an operation that the proxy may not
support. (Instead, the proxy may support only entire objects.) Larger updates, such as
Feature updates, can be tailored by the Windows Update servers to each individual
computer.
To resolve this issue, make sure that the proxy doesn't try to perform any of the
operations that are described in the "Cause" section on Windows Update traffic. For a
list of the URLs that are used by Windows Update, see
