The Win32_PortResource class represents an I/O port on a Win32 computer system.

Quick Start


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


Data type Boolean

The Alias property indicates whether this instance represents the base port address or one of the ranges with an alias. A base port address is a predetermined port address dedicated to a specific service or device. A port alias address is one that a device responds to as if it were the actual address of an I/O port.

Values: $true or $false. A value of $true indicates this instance represents an address alias.


Data type String

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


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 scoping computer system’s creation class name property.


Data type String

The scoping computer system’s name.


Data type String

The Description property provides a textual description of the object.


Data type UInt64

The EndingAddress property contains the ending address of memory mapped I/O


Data type String

The FileName input parameter is a string representing the fully qualified name of the copy of the file (or directory). Example: c:\temp\newdirectory


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 String

The Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.


Data type UInt64

The StartingAddress property contains the starting address of memory mapped I/O. The hardware resource identifier property should be set to this value to construct the mapped I/O resource key.


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.
