    Description

      Essentially the problem is with any AMD/ATI driver but for simplicity let's use the Dell D531 as an example.
      When applying the needed patches (due to CORE-9808)
      just booting up is enough to trigger this problem .

      Below is the registry value that adds the dll, and the associated registry values for the different event handlers:

      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",DLLName,,"Ati2evxx.dll"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Asynchronous,%REG_DWORD%,0
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Impersonate,%REG_DWORD%,1
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Lock,,"AtiLockEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Logoff,,"AtiLogoffEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Logon,,"AtiLogonEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Disconnect,,"AtiDisConnectEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Reconnect,, "AtiReConnectEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Safe,%REG_DWORD%,0
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Shutdown,, "AtiShutdownEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",StartScreenSaver,, "AtiStartScreenSaverEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",StartShell,,"AtiStartShellEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Startup,,"AtiStartupEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",StopScreenSaver,,"AtiStopScreenSaverEvent"
      		 
      HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\AtiExtEvent",Unlock,,"AtiUnLockEvent"
