I am having this same problem with a Dell Optiplex 755. I am industry professional and infrastructure architect for a large consultancy and I have never seen a problem like this.
It is definitely caused by the Windows 10 Update that has come out in the last month or so but not on all machines. I don't think it affects all machines because not all of the 10 or so machines in my home lab Opti 755, 9020, Lat 6430S & 6440) have been
affected. I have however tried it on 4 different Opti 755's and it results in the same error on each of them after the update. All of these machines have been running Windows 10 since it came out with no problems.
This is the error I get.
I have googled this error and have tried literally every solution I could find and nothing worked EXCEPT to force the boot process into recovery mode (power off several times during boot) and then go to the button to revert back to the previous version of
the software. When it does that, I will work again but the automatic update restarts and causes the problem again.
Today I did a FRESH INSTALL of Windows 10 from a Dell labeled Windows 10 install disk. Everything went fine until the update. After the install I joined it to the domain and no prob. I could login to my domain, access the NAS and do everytihing you would
expect. After the update I get the message above.
Any help, guidance, advice or whatever would really be appreciated. I can recreate the problem at will but it does take an image restore and then the update.
Thanks,
R Pierce
