I don't know but here are some guesses based on advice given by others
in the past.  (This is from memory - I have not searched the archives.)

My main guess is that when you copied C:\cygwin, the old file/directory
ownerships were copied.  It would be useful to know if
$ ls -ld ~
and
$ ls -l ~
lists your old user account or some intermediate (copying) user account
as owner(s).

If so, might something like the following work?
$ chown --recursive YOUR_NEW_USER_ACCOUNT ~
or
$ chown --recursive YOUR_NEW_USER_ACCOUNT /cygdrive/c/cygwin
Note:  I've no chown experience; use at your own risk.

Running mkpasswd and mkgroup again might help.

http://cygwin.com/cygwin-ug-net/using-utils.html#mkgroup
etc.

Although this would affect the ownership problem, you might check
environmental variables inherited from Windows, especially CYGWIN,
are as they were on your old machine.

Good luck,
