You have to go to manage users (Start - User Accounts - click User Accounts - Manage User Accounts - add additional users you want or change the properties of the existing user) You will want to copy the files from your former "guest" user to
the new user or administrator user you create. You can simply copy the files from c:\Users\xxxx folder to the new folder. The best way to do the copy is while logged in as the destination user. However, that user will need to have administrative
permissions to gain access to the former user.
