Write Filter WMI Providers (Standard 7 SP1)


Enhanced Write Filter (EWF) and File-Based Write Filter (FBWF) are two of the Embedded Enabling Features of Windows Embedded Standard 7, and help to protect file systems from undesired write access, or to boot and run from read-only file systems.

The Enhanced Write Filter Provider (EWF Provider) and the File-Based Write Filter Provider (FBWF Provider) provide access to the Write Filter APIs (EWFAPI, FBWFAPI) through the Windows Management Instrumentation (WMI) layer. WMI is a standard interface for system management and can be used by native and managed languages such as C, C++, and C#, as well as scripting languages such as VBScript or PowerShell. In addition, WMI offers remote management capabilities which can be used for remote administration of EWF and FBWF.
