Feature update to Windows 10, version 1703 was forced on 6/16/2017. After downloading, it installed 88% and then crashed with blue screen. Now what? It still say "Don't turn off your PC"... Help!

After 7 hrs of blue screen (Fig. 1), I pressed the power button, holding it for a few seconds to turn off PC (Gateway with Intel Core i3). 

Fig. 1.

Then, I turned PC back on, holding the power button for 10 sec. The PC reverted to the previous version of Windows 10. After a while, it begun to download again the "Feature update to Windows 10, version 1703". After downloading, it asked for "restart". The installation took about 1 hr, and crashed producing dark screen and PC apparently dead for several hrs.

Now, my only option would be to turn PC off again - repeating the cycle... My Gateway PC was upgraded from (perfectly well working) Windows 7 to Windows 10 about a year ago, with all updates and patches installed - current as of 06/14/2017. It has the McAfee Security installed.  

At some scenarios, third-party antivirus programs can cause issues in downloading and installing Windows updates. Have you tried to disable the third-party antivirus program you're using and then try to update your computer again?

Note: Antivirus software can help you protect your computer against viruses and other security threats. In most cases, you shouldn’t disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you’re done. If you’re connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

Regards.

Unfortunately, turning off McAfee did not help. Just wasted another 6 hrs of my time on Father's Day ;-( 

The problem, as usual, appeared after restart, producing dark screen for several hrs. Forcing turn off - brings blue screen and crash at 88% installed, with HD not spinning for several hrs. Forcing turn off again - reverts to the previous Win 10 version, and then the cycle starts again and again...

I tried MS "troubleshooter" wu170509.diagcab - it fixed some errors but did not help with installation of the update. The "Win 10 Update Assistant" was not helpful either; installation ends up with "Feature update to Windows 10, version 1703 - Error 0x80246010". 

Let's proceed on running the System File Checker by following the steps on this link. If that doesn't help, run your computer in safe mode and try to run the tool again.

Day 5 of recovering from the latest Windows 10 Update:

The Feature update to Windows 10, ver. 1703 consistently failed at 88% installed (Fig. 2).

Fig. 2

System File Checker did not find any problem. I reverted to previous Win 10 version, then, found and removed all downloaded files of the "Feature update". Now, at last, I have working PC (Fig. 3).

The only problem - I lost my home network (this PC could not see the other computers). I'm working now on setting the "Home group" which may fix this problem. 

Now, the "Update status" does not see any new updates, and PC seems to be "up to date" (Fig. 4).

Unfortunately, there is a threat, that "updates will be downloaded and installed automatically" - which tells me that - willy, nilly - MS is going to screw up my PC again in the near future... 

Glad to know that everything seems to be running smoothly now. As for the automatic updates, that would be the recommended settings for your computer to be always up to date and in case that something comes up, you can check this link Windows Update: FAQ for details like How do I keep my PC up to date, and How do I remove an installed update? Which shows how you can remove a specific update in case it is the source of the issue.
