Anniversary Update Stuck at 1%

I downloaded the Anniversary update on my Alienware M17 laptop (16Gb Ram, i7CPU). The download all went well, but when I restarted, it is still stuck, after 4 hours.
The screen says:

Working on updates 1%
Don't turn off your PC. This will take a while.

I was able to download the Anniversary Update ISO, before I did the Anniversary Update, so I do have that as a backup, but won't that destroy all the data on my C drive?

My questions are:

1. How long did the Anniversary Update take on your PC?

2.. What is the recommended action to take ?

1) I haven't done the upgrade online on any of my 3 systems. I always used an .ISO.

I have an old laptop set to treat WiFi as a metered connection. When I tried to update to the latest build (14393.10) of the Anniversary Update through WiFi, it froze at 6%. I connected it to my router with an ethernet cable, and the update proceeded quickly.

2) If you have the .ISO, you can mount it as a virtual disk. You can upgrade from that (just launch setup.exe). You have the option of preserving your files and "apps".

You could also create a bootable USB drive or DVD from the .ISO. You'd then have the option of doing an upgrade (if you booted into the existing Windows installation) or a clean install (if you booted from the flash drive or DVD).

I suggest spending a little time in the Tutorials here. Not all of them are organized in the most readable fashion, but they cover all the details.

Thank you bobkn for the reply.

I am not familiar with the "virtual disk" concept. How do you mount the ISO ?
I did download the ISO and used ISOtoUSB to put it on a bootable flash drive.

Right click on the ISO and select Mount.

Thanks to everyone for your help. I mounted the ISO and completed the update.
Appreciate it.
