Windows 10: My Windows security was reset on my laptop. Now I can't sign into my laptop.

I have a dell XPS. I broken the mother board on my laptop and sent it back into dell. They fixed it, but reset windows security on it. Windows prompts me to sign into my school or work account, which I do but it keeps say my username or password is wrong. I am using my Microsoft email and password to sign in. Any guidance on this problem would help.

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
