This started with 10159, but I normally watch Task Manager so I can see the download speeds. With 10159 and now on 3 machines with 10162, when the download first starts, the download progress stays at 0%. At that same time, there is a download happening at 50 Mbps and lasts for several minutes. After waiting for the initial download to finish and an additional 10 minutes to see if the install has started, I will try to reset something, like disabling a second network adapter or closing and reopening the Windows update window and the download may start again, but this time the download progress does move and the install will usually complete. On my laptop, I could not convince the download to restart and just left it for maybe an hour or two and it restarted on its own. Maybe the servers have been overloaded or testing is in progress. I do see a notification about "Updating from multiple places".. I also notice there is a new folder on the C: partition named $SysReset which appears to contain logs. Anyway, just wondering if anyone else had noticed this. The good news is no Blue Screens so far. Thanks.
