This is maybe due to the enterprise 2016 (I have not tested yet), so could you please try with a pro/home editions ... you can find an official link in this thread (1st link in the list) : [You must be registered and logged in to see this link.]
Or there is one of your drivers which may be not compatible.
I like LTSB because of no cortana, just simple functional search and no metro apps trash and no windows store by default. I try to remove them from Pro and see if i get them cleaned.
Yes with Pro it works but still LTSB is more liking to me because officially simple working system search and no crapware included at all by default already. LTSB is very good for general usage actually, even when using Directx based software(games, 3d apps and so on). I know that LTSB gets only feature updates when downloading new .iso after years but thats way what i like, rock solid stability.
I just finished testing the Beta 4 with a, not so old, windows 10 enterprise insider preview (build 14393.0) which was released in the end of july 2016. But this is not the LTSB iso.
I tried this iso with your wccf ... and it seems to work with beta 4. I do not have experienced the reboot loop.
Could you please try with Beta 4, which will be released later today, thanks.
