[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]

The IWDFUnifiedPropertyStoreFactory interface is a factory interface that is used to create a unified property store interface.


The IWDFUnifiedPropertyStoreFactory interface has these methods.

Method Description
IWDFUnifiedPropertyStoreFactory::RetrieveUnifiedDevicePropertyStore The RetrieveUnifiedDevicePropertyStore method retrieves a unified property store interface.


A unified property store interface is exposed only from the device object. To retrieve this interface, the driver can call IWDFDevice::QueryInterface or IWDFDeviceInitialize::QueryInterface. If required, the driver can then access the properties before creating the device.

For related information, see Unified Device Property Model.
