I just bought a new Dell Inspiron with Windows 7 installed. I went through the setup and created a password containing an &. I entered the password twice and it was accepted. I wrote it down so I would not forget. Now it tells me "The user name or password is incorrect." I called Dell support and they indicated that the & is not supported in passwords. I got no such indication when I created it. Now they are sending a tech to install a new hard drive. I'm very frustrated; I have a brand new pc I can't use. Could the ampersand be an issue? I even tried entering the p/w without the & and of course that did not work either.
