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. 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 (https://update.microsoft.com) are not returned by Win32_QuickFixEngineering.

Methods

Win32_QuickFixEngineering has no methods.

Properties

Win32_QuickFixEngineering returns 11 properties:

'Caption','CSName','Description','FixComments','HotFixID','InstallDate','InstalledBy',
'InstalledOn','Name','ServicePackInEffect','Status'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName Win32_QuickFixEngineering -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_QuickFixEngineering exist. This is normal behavior.

Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).

Caption

STRING MAX 64 CHAR

A short textual description of the object.

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, Caption

CSName

STRING MAX 256 CHAR

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

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, CSName

Description

STRING

A textual description of the object.

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, Description

FixComments

STRING

Additional comments that relate to the update.

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, FixComments

HotFixID

KEY PROPERTY STRING MAX 260 CHAR

Unique identifier associated with a particular update.

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect

InstallDate

DATETIME

Indicates when the object was installed. Lack of a value does not indicate that the object is not installed.

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, InstallDate

InstalledBy

STRING

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

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, InstalledBy

InstalledOn

STRING

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

Note

This property may use different formats, depending on when the QuickFix was installed. Most systems use a standard date format, such as “23-10-2013”. However, some systems may return a 64-bit hexidecimal value in the Win32 FILETIME format.

®

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, InstalledOn

Name

STRING

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

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, Name

ServicePackInEffect

KEY PROPERTY STRING MAX 260 CHAR

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.

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect

Status

STRING MAX 10 CHAR

Current status of an object. Various operational and nonoperational statuses can be defined. Available values:

$values = 'Degraded','Error','Lost Comm','No Contact','NonRecover','OK','Pred Fail','Service','Starting','Stopping','Stressed','Unknown'

Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property HotFixID, ServicePackInEffect, Status

Selecting Properties

To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.

Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.

Selecting Properties

The code below lists all available properties. Remove the ones you do not need:

$properties = 'Caption',
              'CSName',
              'Description',
              'FixComments',
              'HotFixID',
              'InstallDate',
              'InstalledBy',
              'InstalledOn',
              'Name',
              'ServicePackInEffect',
              'Status'
Get-CimInstance -ClassName Win32_QuickFixEngineering | Select-Object -Property $properties
Limiting Network Bandwidth

If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:

Get-CimInstance -Class Win32_QuickFixEngineering -Property $property | 
Select-Object -Property $property

Selecting Instances

To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).

The parameter -Filter runs a simple query.

Listing all instances where the property Caption starts with “A” 
Get-CimInstance -Class Win32_QuickFixEngineering -Filter 'Caption LIKE "a%"'
Using a WQL Query

The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:

Get-CimInstance -Query "SELECT Name, Description, FixComments, Status FROM Win32_QuickFixEngineering WHERE Caption LIKE 'a%'"

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:

Get-CimInstance -Query "SELECT Name, Description, FixComments, Status FROM Win32_QuickFixEngineering WHERE Caption LIKE 'a%'" | Select-Object -Property Name, Description, FixComments, Status

Accessing Remote Computers

To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.

Authenticating as Current User 
# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_QuickFixEngineering -ComputerName $list 
$result
Authenticating as Different User

Use a CIMSession object to authenticate with a new identity:

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred

$result = Get-CimInstance Win32_QuickFixEngineering -CimSession $session

# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session

$result
