Setting up iCloud on iOS
Step 1: Update your iOS device (optional) — It’s always a good idea to keep your iOS devices up to date, especially with the release of iOS 11. If you haven’t done so already, tap Settings located on your device’s home screen, followed by tapping General, then the Software Update option and the resulting Download and Install button. Wait for the latest version of iOS to download and install before proceeding to Step 2.
Step 2: Enable iCloud — Tap Settings located on your device’s home screen once again. Afterward, tap your name up at the top. You may be prompted to login to your Apple ID, on the next menu click iCloud.
Step 3: Select your iCloud services — iCloud will present you with a list of services, just toggle the slider directly to the right of the applications to choose which ones you’d like to sync across your various devices.
Setting up iCloud on PC
Step 1: Enable iCloud on another device — Apple’s iCloud software is designed to work seamlessly with iOS and MacOS, so begin by enabling and setting up iCloud on another device prior to setting up the software on your Windows PC. Luckily, the two tutorials above will help you get started on both your Mac and iOS device.
Step 2: Download and install the iCloud Control Panel — Unfortunately, Windows does not feature built-in iCloud integration of any kind (surprise, surprise). If you’re mostly a Windows user, you might want to consider a different cloud storage solution instead. Therefore, navigate to the Apple support site and click the blue Download link at the top to download a copy of iCloud Control Panel. Afterward, choose a save location from the resulting window, click the Save button in the bottom-right corner and run the installation software when it’s finished downloading. The bundled wizard will walk you through the entire installation process.
Step 3: Enable iCloud — Launch the iCloud Control Panel and enter your Apple ID and password corresponding to your previously-registered iCloud account. Click the Sign in button in the bottom-right corner when finished.
Step 4: Select your iCloud services — Once signed in, iCloud will present you with four services, including iCloud Drive, Mail, Bookmarks, and contacts and calendars. Check the box directly to the left of the services to choose which ones you’d like to sync across your various devices. Syncing options vary from application to application, but you can typically fine-tune the process within the main Options setting of each service. Click the Apply button in the bottom-right corner when finished.
