First of all I have a case number 1396565630
I try for several days to install the new
last failed on install try on ?28-?8-?2017 - 0x800704c7
under that is says Windows Camera which should get me to a link but does not!
Are you on the Fast release?
I've currently got build 16275 installed without any issues.
I have found however that between the download and install all recent updates require some reboots, even though the system doesn't suggest that it needs any reboots.
Very similar here, no warning on a camera and no camera though.
I am currently running Windows 10 Pro N Insider preview 16257.1, I keep getting updates, but they fail after boot and it rolls back to 16257.1
I will keep going in a loop trying to install the broken updates, so I defer the update for a week hoping it is better.
Here is the update status from my event viewer:
Installation Failure: Windows failed to install the following update with error 0x800704C7: Windows 10 Insider Preview 16273.1000 (rs3_release).
Installation Failure: Windows failed to install the following update with error 0x800704C7: Windows 10 Insider Preview 16281.1000 (rs3_release).
