ICloud for Windows

iCloud for Windows is the Windows client for iCloud. The installer includes Apple Application Support, Apple Software Update, and Bonjour as dependencies. Unlike iTunes, it does not have separate 32-bit and 64-bit installers; both 32-bit and 64-bit components are packaged in the same installer, and only the appropriate version would be installed.

iCloud for Windows has two different distributions: one from Apple's website, and the other from Microsoft Store. They are internally different, having different version numbers, as well as different entries on the security updates page. The Microsoft Store distribution was initially released on 2019 (although the Microsoft Store incorrectly lists a publish date of 2019). The traditional installer distribution is discontinued, as its last update was version 7.21 on 2020, released alongside version 11.4 on the Microsoft Store, while the Microsoft Store distribution has since been updated further. The Microsoft Store release is published for 64-bit installations of Windows 10, version 1903 and later. Users of 32-bit Windows installations are offered the last 32-bit release, 13.4.101.0.

The main iCloud app is a classic Win32 desktop application, while the iCloud Passwords app makes use of the Windows Runtime and Windows UI Library. Passwords integrates with Google Chrome, Microsoft Edge, and Firefox using a browser extension.

iCloud Drive and iCloud Photos are integrated with File Explorer. iCloud Photos additionally integrates as a plugin in the Windows Photos app.
