Black Screen after "Updating" to Windows 10 Anniversary Edition

Updating from Windows 10 Pro 64-bit fully updated. version 1511 build 10586.494

256 GB SSD with OS & essential apps [Office, Norton, etc.]

2TB SATA HD - all other Programs & Games, plus data [pictures, videos, documents, music]

1TB SATA HD - File History backup


i7 Intel Processor 4.00 GHz

Samsung 27" HD Curved monitor

Logitech unified Mouse & backlit keyboard

PC was running smooth as silk, all live tiles functioning as expected, NO browser crashes, freeze-ups, or non-responsive programs, no hardware issues.

Have tried to update to the Anniversary Update in various ways:

-- Manually ran Windows Update

-- Used Windows 10 Upgrade Assistant - disconnected all non-essential peripherals [web cam, all-in-one printer, phone], shut off anti-virus [Norton Security], disconnected my LAN after download was complete

--Tried Media Creation Tool

--Tried Media Creation Tool by using a USB Flash Drive

ALL resulted in same:

--Download & installation seem to go smoothly, no hangs, no errors

--Lock Screen Appears

--I Log In to Microsoft Account [NOTE: PIN does not work, even though that was the method I had been using; I am forced to use Password, even though the PIN option is still showing]

-- Windows goes through its multi-colored pages of "Hi," "Let's Start, etc."

--After that, the Window goes to black ... and stays there .. forever. Mouse cursor is visible & moveable but does nothing. Neither does the keyboard. Ctrl-Alt-Delete does not work. Error pops up: "The sign-in process could not display security and sign-in options when pressing Ctrl-Alt-Del. Please use ESC key or Power Button."  Esc does not work. Have to use Power Button.

--Process Repeats

I tried rebooting into Safe Mode and that appeared to be a step in the right direction. I got in to Windows on the desktop, Start was there, my apps were there. Edge would not work. Windows Update seemed to hang with no progress.

So, I'm thinking, this being an Anniversary celebration & all, this really should not be so difficult. On a machine that was working perfectly, updating its OS should not cause a disaster.

This PC is 2 months old today. I carefully installed & set up everything to my satisfaction. Now Microsoft has screwed it all up. I do NOT want to go through a clean install and all that entails. If that is what it takes, I would prefer to just stay on my version of Windows 10 and forgo all the "enhancements". Can that even be an option? Or, will Windows keep forcing an update on me?

The only positive has been that rolling back to the previous build has proven to be a piece of cake!

Very disappointed. I have spent the better part of the past 24 hours trying to resolve this, to no avail.

So, is this a common or known issue? I find reference to similar predicaments, but they are with test versions earlier on. How is it fixed without starting from scratch?


Well, I couldn't resist playing around. I went into device manager and checked for updates on every listed devise individually. I was surprised to find about a dozen that need updating, including a couple that required a restart.

Then, I performed a clean boot [using msconfig to turn off all programs/services other than MS]. Manually disabled Norton Security for 1hr. Then, rebooted.

Stuck my Windows 10 Anniversary Update flash drive into my PC. Clicked setup, and let it go. I left it connected to the Internet.

Guess what? It worked!!!! 

Then, I just had to figure out which service/program was causing it. The culprit? Stardock's Windows Blinds 10 [a windows customization program]. Disabling that allows a perfect boot up every time. Guess they'll have to release an update on that one.

All is good now!

I hope that this may help someone out there.

 For booting into the repair media use only the BIOS Boot Menu Key.   This avoids problems like repair or installation restarts rebooting into flash stick uncontrollably. 

But first  Boot into BIOS or UEFI firmware into BIOS setup to check that SATA controller has not changed setting. Optimal is AHCI. There is a known issue with MSAHCI driver being installed that can toggle this setting causing no-start.  How to boot into BIOS/UEFI firmware is also detailed for your model in the link I gave above.
