reset laptop password

i could not figure out what forum this should go in, so feel free to move to whatever forum it should be in.
a friend just called, and said he has 2 daughters and 2 dell laptops. his daughters have lost the password to both laptops. is there a way to reset the password without a full reformat? he said his daughters have a lot of music, pictures, ect. and wants to avoid reinstalling windows.
i know that a long time ago there was a jumper on the motherboard that would reset the password on a regular pc. is there such a jumper on a laptop? or is there any free software that would let him reset the passwords? he can not afford a dell tech to fix, and i told him i would see if there was a way to reset it without a format. thanks!
he called me from out of state and due to a bad connection i couldnt find out what model laptops they are. thanks again! sam

 

Password issue

After going through the steps to make a new password, after a week or two, my login credentials are no longer valid. I'm forced to make a new password all over again. It seems to happen if I don't login in a certain period of time. Does our passwords expire???

 

Windows Startup password

Is it possible to remove a startup password without being able to log into the system? A friend's laptop just prompt her today for a password that she never enabled. Now, she does have a standard user account password, but that doesn't work for the startup password. She had the computer for about a year now and it has never asked for a startup password until today.

I tried to use Hiren Boot CD to run a diagnostic on the laptop, but it has a bsod. Windows 10 normal boot crashes as well
