If you don't want to use passwords, try the following:
1. Create a temp folder on the desktop.
2. Go to the Windows directory, and move all *.PWD files to that temp
folder.
3. Restart.
4. When the password dialog comes up, just press return. In other words,
leave it blank.
5. If everything is ok, you can delete the temp folder you created after
you've determined you really don't need the PWD files.
You should now be able to boot up without dealing with the password dialog
at all.
