Reutnes, Thank you for using the Dell Community Forum. You first need to edit your post and remove the system service tag.  Try booting into Safe Mode by pressing the F8 key while booting up. Once in safe mode go into the user accounts in the control panel. Look to see if there is a password for the login and remove or change it.
Good morning, Dell Support! I have on my hands a Dell Inspiron  with a service tag of .  I was helping a friend of mine transfer files from his old computer to the new one.  Anyways, the guy is like 82 years old and the first time he logged in, it asked him to set up a password.  He didn't really want to have that sort of nonsense, so he just clicked Okay a bunch of times until it all went away.  The second time he attempted to log in, it prompted him for a password at the login screen.  The password should (according to him, at least) be blank and being the young techie guy I am he wants me to reset it for him...... except that I really don't know what to do in this scenario.  Ophcrack is what I normally use for this, but it told me that all the passwords were blank so I'm at a loss as to what to do next. Regards, Jake <ADMIN NOTE:Service Tag Removed Per Privacy Legal>
