Did you check /etc/passwd and /etc/group if they contain your user and
your primary group account?  Are you sure you are using a local account?
Compare the information with the output of

  /cygdrive/c/Windows/System32/whoami /user /groups

Important are not the account names, but the account SIDs!  You can change
the user and group names in /etc/passwd and /etc/group whatever you like
(see http://cygwin.com/cygwin-ug-net/ntsec.html).

If you're using a domain account on the machine, you either have to use
the mkpasswd/mkgroup -d option to get the domain and group accounts, or
you can just restrict the files to your user by using the -c option and
append the output to the files, like this:

  $ mkpasswd -c >> /etc/passwd; mkgroup -c >> /etc/group

or, in one go:

  $ mkpasswd -l -c >> /etc/passwd; mkgroup -l -c >> /etc/group
