Problem
By default the Auto Recovery feature is enabled for SSMS and because of this when opening SSMS it may hang or become unresponsive for some time if the previous session was closed unexpectedly. There is not a way to turn this feature off from within SSMS, but we will look at how this can be done by modifying some registry entries.
