Platform Minimum Build
Desktop 1511
Server Core 1709
IoT 1804
HoloLens 1804
The following table lists the minimum Windows 10 version that supports Delivery Optimization:

| Computers running Windows 10 | 1511 |
| Computers running Server Core installations of Windows Server | 1709 |
| IoT devices | 1804 |
| HoloLens devices | 1804 |
By default in Windows 10 Enterprise and Education editions, Delivery Optimization allows peer-to-peer sharing on the organization's own network only, but you can configure it differently in Group Policy and mobile device management (MDM) solutions such as Microsoft Intune.
