Access rights of files from an old laptop's HDD

Question

My old laptop died because of battery issues earlier in the year, and I've managed to get the HDD out before trashing it.

I've bought a new laptop and a USB/SATA plug, and I can access and see the old file tree of my old C: drive (now H:)

I'm trying to recover my personal files from C:\Users\$Username. Unfortunately, I do not have the autorisations, and if I remember my old password I can't remember the name of the laptop (domain controller).

Do you have any way/program which can gain me access rights ?

Thanks you in advance.

Thanks to Ignacia Vazquez-Abrams, I've got the answer :

Taking ownership as administrator. Going to the security pannel of the Folder properties, advanced security settings, and changing the owner.

Thank you all.
