The Win32_QuickFixEngineering?WMI class represents a small system-wide update, commonly referred to as a quick-fix engineering (QFE) update, applied to the current operating system.\nStarting with Windows Vista, this class returns only the updates supplied by Component Based Servicing (CBS). These updates are not listed in the registry. Updates supplied by Microsoft Windows Installer (MSI) or the Windows update site (http://update.microsoft.com) are not returned by Win32_QuickFixEngineering.\nWindows Server 2003 and Windows XP: Instances of this class represent updates found in two places in the registry:\nHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Hotfix\nHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates

Quick Start


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


Data type String

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


Data type String

The CSName property contains the local name of the computer system. The value for this member comes from the CIM_ComputerSystem class.


Data type String

The Description property provides a textual description of the object.


Data type String

The FixComments property contains additional comments relating to the update.


Data type String

The HotFixID property specifies the unique identifier associated with a particular QFE.


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 InstalledBy property identifies who installed the update. If this value is unknown, the property will be empty.


Data type String

The InstalledOn property provides the date and time when the update was installed. If this value is unknown, the property will be empty.


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 String

The ServicePackInEffect property specifies what servicepack was in effect when the update was applied. If no service pack has been applied, the property takes on the value SP0. If it can not be determined what service pack was in effect, this property will be NULL.


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.
