Hi Sarah,
You can export the Windows Contacts as CSV file and import it into CRM.
Go to the Contact area and select Import Data

Then click on the Import Data menu item.

CRM will show the import dialog. All you need to do is to go through the process.
I hope this helps. If my response answered your question, please mark the response as an answer.
