Hi,

For Windows 7 issues, I actually suggest you post the question in the corresponding forum:

As for Emails and Contacts, if it's stored in Office 365, setup Outlook again and you should be able to get them again. If it was stored in a .pst file, you will need to find the .pst file back and then import them back to Outlook.
