Win32_PnPSignedDriver class
The Win32_PnPSignedDriver WMI class provides digital signature information about drivers.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties
The Win32_PnPSignedDriver class has these properties.
ClassGuid
Data type: string
Access type: Read-only
GUID of the device class. Example: "{71A27CDD-11D0-BEC7-08002BE2092F}"
CompatID
Data type: string
Access type: Read-only
Compatibility identifier for the driver. Example: "DETECTEDInternal\ftdisk"
Description
Data type: string
Access type: Read-only
Description of the driver.
DeviceClass
Data type: string
Access type: Read-only
Device class of the driver. Example: "SYSTEM"
DeviceID
Data type: string
Access type: Read-only
Device identifier of the device. Example: "ROOT\FTDISK\0000"
DeviceName
Data type: string
Access type: Read-only
Name of the device.
DevLoader
Data type: string
Access type: Read-only
Device loader for the device.
DriverDate
Data type: string
Access type: Read-only
Build date of the driver (from the manufacturer). Example: "1-25-2001"
DriverName
Data type: string
Access type: Read-only
Name of the driver.
DriverProviderName
Data type: string
Access type: Read-only
Provider of the driver. Example: "Microsoft"
DriverVersion
Data type: string
Access type: Read-only
Version of the driver. Example: "5.1.2427.1"
FriendlyName
Data type: string
Access type: Read-only
Friendly name of the driver. Example: "Communications Port (COM2)"
HardWareID
Data type: string
Access type: Read-only
Hardware identifier for the driver. Example: "ROOT\FTDISK"
InfName
Data type: string
Access type: Read-only
Name of the .inf file that installed the device. Example: "machine.inf"
InstallDate
Data type: datetime
Access type: Read-only
Date the driver was installed. Lack of value does not indicate that the driver is not installed. This property is inherited from CIM_ManagedSystemElement.
IsSigned
Data type: boolean
Access type: Read-only
If TRUE, the driver is signed.
Location
Data type: string
Access type: Read-only
Location of the driver.
Manufacturer
Data type: string
Access type: Read-only
Manufacturer of the driver. Example: "Microsoft"
Name
Data type: string
Access type: Read-only
Qualifiers: Key
Name of the driver. This property is inherited from CIM_ManagedSystemElement.
PDO
Data type: string
Access type: Read-only
Physical device object (PDO). PDOs represent individual devices on a bus. Other drivers for the device attach on top of the PDO. It is always at the bottom of the device stack. Example: "\Device\00000002"
Signer
Data type: string
Access type: Read-only
Signer of driver, if it is signed. Example: "ntbuild"
Started
Data type: boolean
Access type: Read-only
If TRUE, the driver is started. This property is inherited from CIM_Service.
StartMode
Data type: string
Access type: Read-only
Start mode of the driver. This property is inherited from CIM_Service.
Status
Data type: string
Access type: Read-only
Qualifiers: MaxLen (10)
Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Nonoperational statuses include: "Error", "Starting", "Stopping", and "Service". The latter, "Service", can apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, yet the managed element is neither "OK" nor in one of the other states. This property is inherited from CIM_ManagedSystemElement.
The values are:
"OK"
"Error"
"Degraded"
"Unknown"
"Pred Fail"
"Starting"
"Stopping"
"Service"
"Stressed"
"NonRecover"
"No Contact"
"Lost Comm"
SystemCreationClassName
Data type: string
Access type: Read-only
Qualifiers: Key
Value of the scoping computer's CreationClassName property. This property is inherited from CIM_Service.
SystemName
Data type: string
Access type: Read-only
Qualifiers: Key
System name. This property is inherited from CIM_Service.
