Have you refreshed your knowledge of what the relevant config settings are and what they do? <https://wiki.squid-cache.org/SquidFaq/WindowsUpdate> NP: the FAQ is heavy on what they do and values are indications only - so that as these things change you can know what to tweak. > I can do the windows 10 update assistant > manually, and that seems to work ok.

Remove the 'http://' portion. IIRC, this wuCONNECT stuff is for CONNECT messages where the reverse-DNS is needing to match the exact call-home sever WU uses/used. With this broken it cannot do raw-IP fetches it sometimes needs. The "allow windowsupdate localnet" will be allowing CONNECT things this does not match for most fetches. > > > range_offset_limit 10000 MB windowsupdate So very, very large files (ie up to 9GB) will download the *entire* object just to fetch and deliver the final, say 1MB (or worse 32KB) of data to the client. This limit should be much smaller IMO. Each range segment that the WU downloader breaks the update into causes a new full copy to be fetched. Wasting hundreds of multiples of 100-200 MB might be (relatively) acceptable. But many _thousands_ of multiples of 10 GB, not so much. Other than that I'm not seeing anything particularly notable about your config. It may be related to how the D/L is being done. For example, if it uses the Win10 P2P functionality then its unlikely to be going over HTTP as the proxy requires. Any way you can find out if there is a new domain being used for these Win10 features? The list in the FAQ page was last updated for Win8.0 IIRC, so there may be something needing adding there.
