Black Screen of Death Windows 7 Pro

My client has several Dell Opti Desktops with Windows 7.  One began acting strange.  When you reboot Windows starts up with the logo but then we only get a black screen with a movable mouse cursor.  Does not matter which F8 choice I choose I get BSOD.  

Boot Install CD.  "Repair Your Computer".  System Restore fails.  
Command Prompt in "Repair your Computer"
SFC /scannow command says there is a repair pending ... restart
X:\source> is the command prompt.
C: is recovery
D: is OS
E: Windows CD

Regedit at X:\Source>.  Under HKEY_Local Machine Software, Microsoft, Windows NT, Current Version, Winlogon I see Shell= cmd.exe /k start cmd.exe and Userinit=X:\Windows\System32\userinit.exe.  I change Shell to Explorer.exe and Userinit to the C drive.  Reboot, run windows, SOS.  

Have run Symantec's SERT with latest definitions from USB drive and nothing shows up.  Client is using Symantec Endpoint Cloud.  

Suggestions?

I refused to reinstall Windows 7 Pro 64.  This is a Dell Optiplex 3010 and I made sure all the latest and greatest drivers were installed.  There were no dump files.

So I began tracking down the problem.  I was able to restore from a prior period and in groups installed the Microsoft Updates instead of all 62 at once.

That said, I narrowed down the problem to KB2957503 6/10/14.  I also saw where others had the same problem with this update.  I need to stop here as I have other business to attend to.  

Thank you all for your ideas.  I am happy I figured this out on my own.

Back up the computer, format and reinstall Windows. It is too far gone to attempt a Repair Install (which needs a working computer).

One last ditch effort:  Turn the computer all the way off, wait a minute, now start. Does that force a proper repair?  I think not, but try.

I'm going to hold out.  I find these types of problems laugh at me behind my back.  
Am I loading the wrong Registry while in Repair Your Computer mode?

Mucking with the registry is normally both dangerous and futile and half the time creates more problems than it solves (because normally there are multiple locations for the same thing and people only get one).

Please let us know after you have done a full shut down / restart and after you have held out for a while.

Yes.  Full Shutdown.  Powered off.  Restarted.  All the Repair Your Computer tricks.  Odd, though, the last time I was onsite I was able to do a system restore.  This time, I only see three restore points and none will restore.

I think, then, at this point, you really must consider backup and fresh install.

What I don't understand is what could cause two registry entries to change on reboot?  Or am I even reading the local registry when I boot into "RYC" mode?

I did Google my problem and there is much mention of security updates from Microsoft causing this problem in November 2014.  So I thought I would take another look at it before reinstalling the OS.

If nothing can be done . . .

I have a Windows 7 Desktop and 2 Laptops plus my Windows 8 Laptop. Microsoft Updates did not cause any issue to the 4 of them or to any of several dozen client machines.

Please keep us posted.

post the dmp file for more minfo plse
find it in windows\minidumps
if it cannot boot up, hook the drive to a working system to copy the dmp file, or use a live cd, like Knoppix :

I had to research and fix the problem myself as no one could come up with a reasonable solution other than reinstall the OS.
