I have tried the steps in this article that I understood, but I still have
the problem.

I have checked that Dr. Watson my default debugger, however I'm not sure how
to view the log or what to make of it.

I could not find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon
Value = GinaDLL REG_SZ.

I restarted my computer in safe mode and selected Last Known Good
Configuration.

What else do you suggest?

What should I check in safe mode? I have gone into safe mode several times,
trying to solve the problem, but it persists.

I'm not understanding it clearly.
