Q: syncing after PC recovery

Greetings rgbar4,

Welcome to the Apple Support Communities!

I understand that after restoring the operating system on your Windows computer, you are concerned about your data on your iOS devices when you connect to the computer for the first time.

To move your purchased content from your iPhone and iPad back to your computer’s iTunes library, I would suggest re-downloading or transferring your purchases. Please use the steps located in the first attached article to complete this process.

As far as your contacts are concerned, depending of if you use iCloud on your Windows computer, there are a couple of different methods to syncing that data. If you do not use iCloud and would like to sync your contacts as you would your music, please follow the steps in the next attached article. Your contacts will be listed in the Info section in the sidebar.

If you are using iCloud to sync your contacts with your Windows computer, please use the next article as a resource.
