We are having issues getting Windows 10 distributed to slower sites, so we reached out to Microsoft, which suggested using Express updates. We turned it on and during testing experienced severe performance issues. It took 40 hours to download and install patches using Express Updates. Another machine on the same subnet, same DP, NOT using express updates took 15 minutes to download, install, and reboot. Not to mention the package grew from 4GB to 24 GB.
We reached out to Microsoft with our testing results and expressed our concerns; they confirmed "there was a bug that they found that causes clients to create numerous BITS jobs (one for each byte range for the deltas to the package). Each of those jobs has it's own overhead, and latency amplifies that." They did confirm the fix for express updates is in escrow for the next Current Branch release, which should be in the next month or so. As others have stated Express updates are not ready for prime-time.

I was really looking forward to getting this up and running after the 1702 upgrade but I am a little disappointed with the results I am seeing. I understand the initial download is larger and I am okay with that, my patch package jumped from 13.1GB to nearly 44GB so the 2-3X size increase was pretty accurate. My issue is the time that it is taking to install the cumulative update, it is taking almost 3+ hours on my test machines. The machines are all W10 1607 with the latest April update applied, everything in the log files (deltadownload.log) indicates all is well and they are using the express files to install. It just takes forever to apply the update. Is anyone else experiencing very long install times using the express install files? I am going to test a 1703 machine today to see if it makes any difference. Thanks Carl
