The Win32_PageFileUsage 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 runtime state of the page file.

Namespace value is root/CIMV2.
WMI Provider value is CIMWin32.


  • AllocatedBaseSize
  • The AllocatedBaseSize property indicates the 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: 178MB

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

  • CurrentUsage
  • The CurrentUsage property indicates how much of the total reserved page file is currently in use.

  • Description
  • The Description property provides a textual description of the object.

  • 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.

  • Name
  • The Name property indicates the name of the page file.
    Example: C:\PAGEFILE.SYS

  • PeakUsage
  • The PeakUsage property indicates the highest use page file.

  • 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.

  • TempPageFile
  • The TempPageFile property specifies whether a temporary page file has been created, usually because there is no permanent page file on the current computer system.
