A note from SFC tutorial:
SFC quite often requires several runs to repair all errors. If the message as in your screenshot is shown you should just restart PC and then run SFC /SCANNOW again.If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command up to 3 times with Fast Startup turned off and restarting the computer after each time to completely fix everything that it's able to.
Tutorial: SFC Command - Run in Windows 10
I'm still leaning to the view is that it's something broken in the existing installation which the reinstall can't configure to install 1607.
The fact that DISM found issues which it can't fix automatically also bears out that something is wrong with the original install.
That said, it may be that the combination of switching off IIS and running SFC may have cleared enough issues to allow a Restart and reinstall. Having as few devices as possible connected during an install isn't a bad approach either.
I'm not unduly bothered that HP haven't issued Windows 10 drivers - the laptop I use day-to-day doesn't even have Windows 7 drivers on the OEM's website and it still runs Windows 10. You could be unlucky though
I see Kari's just posted while I was writing that- I think Kari knows more than me about such things.
The last resort is to clean install Windows from scratch, but that means taking backups (I'd have more than one) deleting everything and reinstalling all software, so is not an easy option, so I'd be trying other things first.
Counting the first time I ran sfc, I have run it a total of 4 times with a reboot between each one. It still says the same things a the cmd pic I inserted before. I take all you folks say very seriously, and follow your instructions as close as I understand them. Sadly, I must leave for a couple of hours, but will return to this discussion asap.
Ok, I'm back. Just before logging in here, I unchecked iis, unplugged my USB drives, disabled Win Defender, printer is off, and tried the update again. Same failure as all the rest.
Do you have a spare empty HDD? If so you could reassure yourself that 1607 can be installed and run on your PC by swapping out your drive, putting the empty drive in and doing a clean install. If that works you would have ruled out a hardware conflict, if it doesn't you may get more clues as to what the problem is.
Are you doing the upgrade from a .iso? That's an install disk, you could burn it to a DVD and boot from that.
Or you could use the Media Creation Tool to make bootable USB install media.
Or you could make a Recovery Drive on a sufficiently large USB, then mount the .iso and copy the files from it to the recovery USB. Boot to a command prompt and run Setup.
