For Windows 7, follow these steps (they are somewhat similar on Windows Vista and XP as well)...
My computer -> Local Disk -> Users -> ADMIN ACCOUNT NAME -> Favorites
Simply copy the favorites folder in to the limited account's folder, which is found under "Users" as well.
The overall path for Windows 7 is C:\Users\ACCOUNTNAME\Favorites
If you're using a different operating system and still can't figure it out, let me know.
