Hi there Kfilby!
In order to link your PC and iPad with iCloud, you will want to download the iCloud Control Panel for Windows. A link to download that can be found right here:
iCloud Control Panel 2.1.2 for Windows

You will also need to sign into your iCloud account on your iPad if you haven't already. You can do that by going to Settings -> iCloud and signing in there. Thanks for coming to the Apple Support Communities!
Regards,
Braden
