Hi newcomer and welcome to the Tom's hardware forum.
The Scotteq is a good option for only export the contacts.Here
you can find an option that export your contacts and keeps the autocomplete feature (If you remember the names of your contacts). Look for the .nk2 tittle and follow the steps. After that you are in the folder, copy ALL the files and paste in the same location on the laptop, don't worry, works fine for vista and 7.
Now, you have all your contacts and the autocomplete feature.
