The roll out starts today via a Microsoft Store update to the Photos app. It should be available to all Windows 11 customers by the end of the month.
We know that many Windows customers have photo and video collections on their iPhones that they would like to be able to view on their PC. This iCloud Photos integration will make it easier for those with an iPhone to have direct access to all their cherished memories in one organized place and is another step in our continued efforts to make experiences on Windows 11 seamless.
To bring your iCloud Photos into the Photos app, make sure your Photos app is updated and then install the iCloud for Windows app. From there, sign in and choose to sync your photos, and all your iCloud Photos content will appear automatically in your Photos app.
