I did install the Insider Preview, without any problems about a week ago. But I did not test it. I got no errors while installing. But had to be patient, because rebooting and installing took some time where I was tempted to belive the device got stuck and nearly turned it off while installing.
The reason I did not test the insider preview: I got the startmenu-bug and tried to repair it using the insider preview. This did not help so I reverted to the Windows-Refresh-Function.
