I have Dell XPS L502X laptop running the latest version of Windows 10 Anniversary update. It has 4 GB RAM, 500 GB HDD, 1 GB NVidia graphics card, and 3rd generation Intel core i3 processor. It's pretty fast and I have performed a clean installation of Windows 10 last week itself.
The problem is with the installer or perhaps there is some conflict with some Windows 10 code due to which it freezes in between that too without any indication and time out messages. I once waited for 9 hours but it stayed at 99%. It's really frustrating.
I am not an insider. But I am learning UWP.
Here is the screenshot for your reference.
