"Worn Out Retread" escribió
I am wondering if I can use a backup made while using Vista Home Premium 64
to populate Windows 7 with my data and settings made using said backup.

Has anyone done this?

Data you can simply copy them to another disc or folder. Typically your user
folder and subfolders (My documents, My pictures, Favorites an so on).
Settings like mail accounts, you can backup and later restore them by using
programs like Windows Vista Manager (Fantastic program, same as Window 7
Manager for Seven)..
Any other settings you'd like to save?
