After using this build for just over a day I think the prospect is looking very good for the Anniversary release. Finding little to dislike in this release
Just activated Windows 10 Build 14385 in a VMware WS VM using the Activation Troublewhooter. No problems at all.
Going direct to the manufacturer's own update site and downloading the correct full update available would still be a recommendation however to insure the correct drivers are what are going on as well as being on fully. I run into this type of problem with two older expansion cards one being a discontinued tv tuner card still in use where I have to grab the 8.1 x64 drivers and app for a similar but for a different PCI Express not PCI model card.
The web updater option seen with the Creative X-FI XTreme Audio also 8.1 gets the Support 1.2 and then puts on the 1.5 updated for 10 driver set not found at the support site as the alternate route for the sound card. Yet I am still able to keep older wares running at this time by innovating things a bit.
Next experiment, clean install MS ISO 14366, which before didn't have the endless loop. But this time it did which makes me think the problem is at MS end. I used Kari's tutorial to stop the endless loop. Now waiting for 14385 to appear.
I'm "up to date" at 12:40 PM Central Time.
And while I go out to get a water hose repair kit and DentaBones for Gracie, it will most likely drop!
At this you would likely see the 361 or 366 as the first Insider build when enabling the option following a clean install and then subsequently moving onto the next newer over time. With the direct download of the last latest build which now would be the 379 or 383 skipping the updates option by leaving that box unchecked at either upgrade by update or clean install should allow you to manually check for things at the support sites without running into the looping issue.
Actually I did download the MS tool indicated in the guide Kari pointed to but as of yet have actually had any occasion to use it. Disabling the WU entirely by going into Settings>Update & Security>Advanced options there until getting the essential hardware updates on you find at the support sites being sure to keep those backed up in a safe place as well once attained will then and should later allow you to receive the normal MS updates without any further issues.
This was what I was trying to explain before if you are still finding the same situation of looping. Basically you turn the Windows update function off long enough to manually track down what you need to get past the one or more items hanging on you before returning to the normally functions. If one thing doesn't work you simply try another to see if you get results.
New build coming up soon possibly.
