How to Turn On or Off Share Across Devices for Apps in Windows 11
You turn on or off the “Share Across Devices” feature in Windows 11 to control app continuity between your Microsoft-linked devices.
This setting allows specific Windows 11 apps to share their experiences, like starting a document on one PC and finishing it on another, provided you’re signed in with the same Microsoft account.
You can enable or disable this functionality through the Windows 11 Settings app, typically found under the “System” > “Shared experiences” section, version 22H2 and later.
Open Settings, go to Apps, then Advanced app settings, and click Share across devices. Select “Off,” “My devices only,” or “Everyone nearby” to manage app continuity between your Windows 11 devices.
What is Share Across Devices?
“Share Across Devices” (also called Project Rome or “Shared Experiences”) lets your apps work together on your different devices. For example, you could start reading an article on your PC and continue on your tablet without losing your place.
You can choose to share with:
- My devices only (default) – only your devices signed in with the same Microsoft account can share apps.
- Everyone nearby – anyone close to you can share app experiences with your PC.

What does turning off share across devices do?
To avoid any potential issues, we strongly recommend turning off this option on all your Apple devices connected to the same Apple ID. Don't worry—this won't disable Screen Time on your devices. It simply prevents the time tracked on each device from being merged.
