Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3194496) - Error 0x80d05001
Definition Update for Windows Defender - KB2267602 (Definition 1.229.676.0) - Error 0x80d05001
Internet traffic has been pegged to our account max for over a week due to windows update repeatedly failing on multiple machines while attempting updates subsequent to the "anniversary " update. Every day a dozen or so systems will all report the same failures, with the same list of failed updates repeating on each system day after day. At this point we have to shut down 75% of the systems in the business just to be able to email an image to a client. To be able to successfully update a system, we shut down every system except one each night so it has full access. Our firewall is actively monitored and virtually all traffic is coming from Microsoft IP's. This is beyond ludicrous! All systems are similar, less than 2 year old desktop I5 systems with 4-8 GB RAM running MS office and a practice management system. Essentially no user internet activity is allowed. We have tried using the setting where files are downloaded to one system on the LAN and those files are supposed to be made available across the LAN if that is the best or fastest source. This setting is being ignored. If we restrict the business to only one workstation, then it will usually be updated successfully overnight, indicating that the problem is not with workstation hardware. It will take a month to get the business past this issue, assuming that this is a one-time problem and not an indication of future performance. Any hints on how to break this log jam would be great.
