I desperately need some help with resetting our PC. Our oldest daughter had this laptop for school and does not remember her password. I’ve been trying to reset it but every time I try I get an error message that says “Additional free space is needed on the drive where Windows is installed. Free up some space and try again.” Since I don’t have her password I have no way of freeing up space. Is there another way for me to reset it or to create another Windows login??
Unfortunately if you don't know the Windows password, and there is no space, you can't reset the PC.
But you can make it usable again as follows...
With another working Windows PC, use the media creation tool to create a bootable W10 installation flash drive from the link below. You will need an 8 GB USB flash drive, and you want to create the 64 bit installation media.
