Probably because you had no mount table.

Setup read the file that stores the choices of what packages you've
selected (from the file /etc/setup/installed.db) and saw that this list
corresponds to the most up-to-date versions of those packages available,
so there was nothing for it to install.  But since there was no mount
table, it did recreate that.

Just chown the file, "chown username filename".  In order for this to
work though you might need to recreate your /etc/passwd and /etc/group
files, as that is where Cygwin gets the username <-> SID mapping.  Or
you could just do it in explorer, right click, properties, take
ownership.

You'll have to reinstall any services that you had installed before.

Essentially, to sum up your question: Things that are stored as regular
files survived the reinstall, things that are stored in the registry did
not.  And additionally, Windows considers your new account different
from the previous one, though it may have the same name.
