Win32_PageFileUsage class
The Win32_PageFileUsage WMI class represents the file used for handling virtual memory file swapping on a Win32 system. Information contained within objects instantiated from this class specify the run-time state of the page file.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties and methods are in alphabetic order, not MOF order.

Properties
The Win32_PageFileUsage class has these properties.
-
AllocatedBaseSize
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: MappingStrings ("Win32API|MEMORYSTATUS|dwTotalPageFile"), units ("megabytes")
Actual amount of disk space allocated for use with this page file. This value corresponds to the range established in Win32_PageFileSetting under the InitialSize and MaximumSize properties, set at system startup.
Example: 178
-
-
Caption
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64), DisplayName ("Caption")
A short textual description of the object.
This property is inherited from CIM_ManagedSystemElement.
-
-
CurrentUsage
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: MappingStrings ("Win32API|MEMORYSTATUS"), units ("megabytes")
Amount of disk space currently used by the page file.
-
-
Description
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Description")
A textual description of the object.
This property is inherited from CIM_ManagedSystemElement.
-
-
InstallDate
-
-
Data type: datetime
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5"), DisplayName ("Install Date")
Indicates when the object was installed. Lack of a value does not indicate that the object is not installed.
This property is inherited from CIM_ManagedSystemElement.
-
-
Name
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Key, Override ("Name"), MappingStrings ("WMI")
Name of the page file.
Example: "C:\PAGEFILE.SYS"
-
-
PeakUsage
-
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: MappingStrings ("WMI"), units ("megabytes")
Highest use page file.
-
-
Status
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (10), DisplayName ("Status")
String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).
Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states.
This property is inherited from CIM_ManagedSystemElement.
Values include the following:
-
-
OK ("OK")
-
Error ("Error")
-
Degraded ("Degraded")
-
Unknown ("Unknown")
-
Pred Fail ("Pred Fail")
-
Starting ("Starting")
-
Stopping ("Stopping")
-
Service ("Service")
-
Stressed ("Stressed")
-
NonRecover ("NonRecover")
-
No Contact ("No Contact")
-
Lost Comm ("Lost Comm")
TempPageFile
-
Data type: boolean
-
Access type: Read-only
-
Qualifiers: MappingStrings ("Win32Registry|System\\CurrentControlSet\\Control\\Session Manager\\Memory Management|TempPageFile")
If true, a temporary page file has been created, usually because there is no permanent page file on the current computer system.
Remarks
The Win32_PageFileUsage class is derived from CIM_LogicalElement.
