What is Wdf01000?
The genuine Wdf01000.sys file is a software component of Microsoft Windows Operating System by Microsoft Corporation.
The filename "Wdf01000.sys" reflects a specific major ("01") and minor ("000") version of the Microsoft Windows Kernel-Mode Driver Framework (KMDF) Runtime, which resides in "C:\Windows\System32\drivers". It runs continually in the background as a Windows service. There are both an "in-memory" and an "on-disk" version. Its function can be compared to that of the Common Language Runtime (CLR) for managed code in the .NET Framework. For kernel-mode drivers that are specifically written to use it, it handles Power Management, Plug and Play, and other aspects of the interface between the OS and a device so that they do not have to be written in the driver. Windows Vista included a version by default. Windows XP and later do not; the package installing a KMDF driver requires a "co-installer". If the co-installer's version is newer than the runtime's in-memory or on-disk version, an update and reboot is required.
