Error: Information (in the registry) is incomplete or damaged. (Code 19)

I faced a problem with my CD/DVD drive that it was being detected in CMOS and system was also booting using it. But 'My Computer' was not showing its icon. Device Manager was showing that the driver is corrupt. Updating the driver didn't solve the problem. Device Properties was showing the error as in Subject.

Solution that I found workable is as to be shared with you all.
