On the iPad and iPhone;
Then, sign in with your Apple ID. Make sure all services are turned ON that you would like to use.
If you are already signed into iCloud then make sure both devices are using the same Apple ID.
It's usually best to use the same Apple ID as you use for the iTunes and App Stores, when possible.
On your Windows 7 PC you will then need to install "iCloud Control Panel for Windows". http://support.apple.com/kb/dl1455
