-When you use feature updates policy to deploy Windows 11, you can target the policy to any of your Windows 10 devices and only devices that meet the Windows 11 minimum requirements will upgrade. Devices that don’t meet the requirements for Windows 11 won’t receive the update and remain at their current Windows 10 version.

See [Update behavior when multiple policies target a device](#update-behavior-when-multiple-policies-target-a-device).
 
 When there are multiple versions of Windows 11 available, you can choose to deploy the latest build. When you deploy the latest build to a group of devices, those devices that already run Windows 11 will update while devices that still run Windows 10 will upgrade to that version of Windows 11 if they meet the upgrade requirements. In this way, you can always upgrade supported Windows 10 devices to the latest Windows 11 version  even if you choose to delay the upgrade of some devices until a future time.

It’s the [same process](#create-and-assign-feature-updates-for-windows-10-and-later-policy) though instead of selecting a Windows 10 version, you’ll select a Windows 11 version from the *Feature update to deploy* dropdown list.

+## Update behavior when multiple policies target a device:
+
+Consider the following points when feature update policies target a device with more than one update policy, or target a Windows 10 device with an update for Windows 11:
+
+- Each Windows feature update policy supports a single update. When a device is targeted by more than one policy, it might be targeted with multiple update versions.  
+
+- The Windows Update service can only offer a device one feature update at a time, and always offers the latest update version that targets the device.
+
+- Because Windows 11 updates are considered to be later versions than Windows 10, the service always offers the Windows 11 update to a device targeted by both Windows 10 and Windows 11 updates. This is done because deploying a Windows 11 update to a Windows 10 device is a supported upgrade path.
+
+- The Windows Update for Business deployment service can’t determine that a device can’t run Windows 11. Therefore, if a Windows 10 device that can’t run Windows 11 is targeted with a Windows 11 update, Windows 10 updates will not be offered automatically. In this case, remove the not eligible device from the Windows 11 policy and assign the device to a Windows 10 feature update policy.
