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. Starting 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.

Windows Server 2003, Windows XP, Windows 2000, and Windows NT 4.0:  Instances of this class represent updates found in two places in the registry:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Hotfix

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates

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.

Members

The Win32_QuickFixEngineering class has these types of members:

• Properties

Properties

The Win32_QuickFixEngineering class has these properties.

Caption

Data type: string

Access type: Read-only

Short textual description of the object.

CSName

Data type: string

Access type: Read-only

Qualifiers: MaxLen (256)

Local name of the computer system. The value for this property comes from the CIM_ComputerSystem class.

Description

Data type: string

Access type: Read-only

Description of the object.

FixComments

Data type: string

Access type: Read-only

Additional comments that relate to the update.

HotFixID

Data type: string

Access type: Read-only

Qualifiers: Key, MaxLen (260)

Unique identifier associated with a particular update.

InstallDate

Data type: datetime

Access type: Read-only

Object was installed. This property does not require a value to indicate that the object is installed.

InstalledBy

Data type: string

Access type: Read-only

Person who installed the update. If this value is unknown, the property is empty.

InstalledOn

Data type: string

Access type: Read-only

Date that the update was installed. If this value is unknown, the property is empty.

Name

Data type: string

Access type: Read-only

Label by which the object is known. When subclassed, the property can be overridden to be a key property.

ServicePackInEffect

Data type: string

Access type: Read-only

Qualifiers: Key, MaxLen (260)

Service pack in effect when the update was applied. If no service pack has been applied, the property takes on the value SP0. If it cannot be determined what service pack was in effect, this property is NULL.

Status

Data type: string

Access type: Read-only

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.

The values are:

"OK"

"Error"

"Degraded"

"Unknown"

"Pred Fail"

"Starting"

"Stopping"

"Service"

Remarks

The Win32_QuickFixEngineering class is derived from CIM_LogicalElement.

Because updates are stored in two places, an enumeration of this class can result in duplicates.
