Win32_PnPSignedDriver Class

The Win32_PnPSignedDriver class provides digital signature information about drivers
Namespace value is root/CIMV2.
WMI Provider value is WhqlProvider.


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

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

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

  • CreationClassName
  • 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.

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

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

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

  • DeviceName
  • The DeviceName property is the name of the device

  • DevLoader
  • The DevLoader property is the Device Loader for the device

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

  • DriverName
  • The DriverName of the driver

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

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

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

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

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

  • InstallDate
  • 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.

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

  • Location
  • The Location property is the Location of the driver

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

  • Name
  • 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.

  • PDO
  • 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

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

  • Started
  • Started is a boolean indicating whether the service has been started (TRUE), or stopped (FALSE).

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

  • Status
  • 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.

  • SystemCreationClassName
  • The scoping System's CreationClassName.

  • SystemName
  • The name of the system that hosts this service


  • StartService
  • The StartService method places the Service in the started state. It returns an integer value of 0 if the Service was successfully started, 1 if the request is not supported and any other number to indicate an error. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.

  • StopService
  • The StopService method places the service in the stopped state. It returns an integer value of 0 if the service was successfully stopped, 1 if the request is not supported and any other number to indicate an error.
