I am trying to share folders between my Win7 and Win10 laptops. From my Win10 laptop, I can open File Explorer, type \\win7pc\ and am able to access all folders in it. From my win7 laptop, when I open file explorer and type \\win10pc\, the Enter Network Password dialog opens. It wants me to enter a user id and password. I'm not really sure what to enter here because when I sign on to my win10 laptop, I just use the fingerprint reader or I type in a PIN.
