You can copy any file from one account to another from windows explorer.
From an admin account right click Start and select explore all users
Locate the user name that has the files you need and click on it.
Copy any files you need from that user name. For example open Username/Start Menu/Programs folder and copy any missing shortcuts and paste them into the other username2's Start Menu/Programs
Continue until you have everything you need and you can delete the other login if you like. Hope this helps
