It is supposed that this mistake is supposed to be caused by the lately launched security updates by Microsoft. However, the company rejects this. British security firm Prevx also established that convinced users are facing the Black Screen of Death after logging in.

Also, a change in registry entry price -
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell was observed. Microsoft examined their November Security Updates inside and refuted stating that the reports were imprecise.
