Home Reference WMI Reference root CIMV2 Win32_PnPSignedDriver


The Win32_PnPSignedDriver class provides digital signature information about drivers

Quick Start


In this WMI class, all WMI properties are read-only. You can only read values but not change them.


Data type Object


Data type String

The Caption property is a short textual description (one-line string) of the object.


Data type String

The ClassGUID property is the ClassGUID of the device e.g. {71A27CDD-812A-11D0-BEC7-08002BE2092F}


Data type String

The CompatID property is the CompatID for the driver e.g. DETECTEDInternal\ftdisk


Data type String

CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.


Data type String

The Description property is the Description of the driver e.g. Volume Manager


Data type String

The DeviceClass property is DeviceClass of the driver e.g. SYSTEM


Data type String

The DeviceID property is the DeviceID of the device e.g. ROOT\FTDISK\0000


Data type String

The DeviceName property is the name of the device


Data type String

The DevLoader property is the Device Loader for the device


Data type DateTime

The DriverDate property is the Date of the driver e.g 1-25-2001


Data type String

The DriverName of the driver


Data type String

The ProviderName property is the Provider of the driver e.g. Microsoft


Data type String

The DriverVersion property is the version of the driver e.g. 5.1.2427.1


Data type String

The FriendlyName property is the array of FriendlyName/Caption of the driver e.g. Communications Port (COM2)


Data type String

The HardwareID property is the HardwareID of the driver e.g. ROOT\FTDISK


Data type String

The InfName property is the name of the Inf file which installed this device e.g. machine.inf


Data type DateTime

The InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.


Data type Boolean

The IsSigned property is the signature status of driver that is it represents whether the driver is signed or not


Data type String

The Location property is the Location of the driver


Data type String

The Manufacturer property is the Manufacturer of the driver e.g. Microsoft


Data type UInt32


Data type String

The Name property uniquely identifies the service and provides an indication of the functionality that is managed. This functionality is described in more detail in the object’s Description property.


Data type String


Data type String


Data type String

The PDO property represents Physical Device Object e.g \Device\00000002 PDOs represent individual devices on a bus to a bus driverA bus driver creates a PDO for each device that it enumerates on its bus.The PDO represents the device to the bus driver. Other drivers for a device attach device objects on top of the PDO–the PDO is always at the bottom of the device stack


Data type String

The Signer property is the signer of driver if it is signed e.g. ntbuild


Data type Boolean

Started is a boolean indicating whether the service has been started ($true), or stopped ($false).


Data type String

StartMode is a string value indicating whether the Service is automatically started by a System, Operating System, etc. or only started upon request.



Data type String

The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are “OK”, “Degraded” and “Pred Fail”. “Pred Fail” indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are “Error”, “Starting”, “Stopping” and “Service”. The latter, “Service”, could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither “OK” nor in one of the other states.

'OK','Error','Degraded','Unknown','Pred Fail','Starting','Stopping','Service','Stressed','NonRecover','No Contact','Lost Comm'


Data type String

The scoping System’s CreationClassName.


Data type String

The name of the system that hosts this service


Data type UInt32
