WI: What if Tsarevich Dmitri never died?

In 1591 the son of Ivan the Terrible, Tsarevich Dmitri, was found dead. Many blamed the death on the current regent Boris Gudonov, resulting in a series of pretenders showing up and creating the Time of Troubles, which ended the Rurik dynasty and ushered in the Romanovs.
So what if Dmitri never died? What if he didn't cut his throat on accident or wasn't murdered? With the Time of Troubles butterflied, how does it affect Eastern Europe and the world?
