Download iTunes Store purchases on PC
You can turn on automatic downloads for up to 10 computers and devices, combined. You can authorise up to five computers at a time with an Apple ID.
Note: Some items may not be available for automatic download in all countries or regions.
In the iTunes app on your PC, choose Edit > Preferences, then click Downloads.
Below Automatic Downloads, select the types of content (Music, Movies and TV Shows) you want to download automatically.
If iTunes is open when you make a purchase on another computer or device, the purchased item is downloaded to your computer at the same time that it’s downloaded to the other device. If iTunes isn’t open at the time of purchase, the item is downloaded automatically the next time you open iTunes or when you choose Account > Check for Available Downloads.
To find out how to turn on automatic downloads on your device, see the user guide for iPhone, iPad or iPod touch. For a device that doesn’t use the latest version of iOS or iPadOS, get the user guide from the Apple Support Manuals website.
