Thanks Brian.� Made some progress.

$ getfacl /home/$USER
# file: /home/mukx
# owner: mukx
# group: mukx
user::rwx
group::rwx
other:rwx
default:user::---
default:group::---
default:other:rwx

The default DACL's look strange with other enabled.� Looked at the root

$ getfacl /
# file: /
# owner: Administrators
# group: Administrators
user::rwx
group::rwx
other:rwx
default:user::---
default:group::---
default:other:rwx

Used setacl

$ getfacl /home/mukx
# file: /home/mukx
# owner: mukx
# group: mukx
user::rwx
group::rwx
other:rwx
default:user::rwx
default:group::rwx
default:other:rwx

startxwin will now run when the initial cygwin64 terminal is started 
with "run as administrator" but not otherwise from the same windows user 
who is the system administrator.
