You can select "re-install" in the package manager. Just toggel the icon 
next to "All" (at the top) until it reads "re-install".

I like to keep a back up of anything I have added or configured, such as 
the path folders and such. That way, if I have to wipe out the cygwin 
folder and start again, it is not so much trouble. I would be nice if 
the package manager could dump it's current state to an xml file or 
something like that so I don't have to remember everything I have 
installed. Maybe there is a feature like that, but I'm not aware of it.

I don't know if re-install keeps your configurations or not, so that is 
something to find out about or prepare for.
