The Win32_OSRecoveryConfigurationâWMI class represents the types of information that will be gathered from memory when the operating system fails. This includes boot failures and system crashes.
Methods
Win32_OSRecoveryConfiguration has no methods.
Properties
Win32_OSRecoveryConfiguration returns 15 properties:
'AutoReboot','Caption','DebugFilePath','DebugInfoType','Description',
'ExpandedDebugFilePath','ExpandedMiniDumpDirectory','KernelDumpOnly','MiniDumpDirectory','Name',
'OverwriteExistingDebugFile','SendAdminAlert','SettingID','WriteDebugInfo','WriteToSystemLog'
Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration -Property *
Most WMI classes return one or more instances.
When
Get-CimInstance
returns no result, then apparently no instances of class Win32_OSRecoveryConfiguration 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).
AutoReboot
System will automatically reboot during a recovery operation.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, AutoReboot
Caption
Short textual description of the current object.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, Caption
DebugFilePath
Full path to the debug file. A debug file is created with the memory state of the computer after a computer failure.
Example: “C:\Windows\Memory.dmp”
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, DebugFilePath
DebugInfoType
Type of debugging information written to the log file.
DebugInfoType returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$DebugInfoType_map = @{
0 = 'None'
1 = 'Complete memory dump'
2 = 'Kernel memory dump'
3 = 'Small memory dump'
}
Use a switch statement
switch([int]$value)
{
0 {'None'}
1 {'Complete memory dump'}
2 {'Kernel memory dump'}
3 {'Small memory dump'}
default {"$value"}
}
Use Enum structure
Enum EnumDebugInfoType
{
None = 0
Complete_memory_dump = 1
Kernel_memory_dump = 2
Small_memory_dump = 3
}
Examples
Use $DebugInfoType_map in a calculated property for Select-Object
<#
this example uses a hashtable to translate raw numeric values for
property "DebugInfoType" to friendly text
Note: to use other properties than "DebugInfoType", look up the appropriate
translation hashtable for the property you would like to use instead.
#>
#region define hashtable to translate raw values to friendly text
# Please note: this hashtable is specific for property "DebugInfoType"
# to translate other properties, use their translation table instead
$DebugInfoType_map = @{
0 = 'None'
1 = 'Complete memory dump'
2 = 'Kernel memory dump'
3 = 'Small memory dump'
}
#endregion define hashtable
#region define calculated property (to be used with Select-Object)
<#
a calculated property is defined by a hashtable with keys "Name" and "Expression"
"Name" defines the name of the property (in this example, it is "DebugInfoType", but you can rename it to anything else)
"Expression" defines a scriptblock that calculates the content of this property
in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
value to its friendly text counterpart:
#>
$DebugInfoType = @{
Name = 'DebugInfoType'
Expression = {
# property is an array, so process all values
$value = $_.DebugInfoType
$DebugInfoType_map[[int]$value]
}
}
#endregion define calculated property
# retrieve the instances, and output the properties "Caption" and "DebugInfoType". The latter
# is defined by the hashtable in $DebugInfoType:
Get-CimInstance -Class Win32_OSRecoveryConfiguration | Select-Object -Property Caption, $DebugInfoType
# ...or dump content of property DebugInfoType:
$friendlyValues = Get-CimInstance -Class Win32_OSRecoveryConfiguration |
Select-Object -Property $DebugInfoType |
Select-Object -ExpandProperty DebugInfoType
# output values
$friendlyValues
# output values as comma separated list
$friendlyValues -join ', '
# output values as bullet list
$friendlyValues | ForEach-Object { "- $_" }
Use $DebugInfoType_map to directly translate raw values from an instance
<#
this example uses a hashtable to manually translate raw numeric values
for property "Win32_OSRecoveryConfiguration" to friendly text. This approach is ideal when
there is just one instance to work with.
Note: to use other properties than "Win32_OSRecoveryConfiguration", look up the appropriate
translation hashtable for the property you would like to use instead.
#>
#region define hashtable to translate raw values to friendly text
# Please note: this hashtable is specific for property "Win32_OSRecoveryConfiguration"
# to translate other properties, use their translation table instead
$DebugInfoType_map = @{
0 = 'None'
1 = 'Complete memory dump'
2 = 'Kernel memory dump'
3 = 'Small memory dump'
}
#endregion define hashtable
# get one instance:
$instance = Get-CimInstance -Class Win32_OSRecoveryConfiguration | Select-Object -First 1
<#
IMPORTANT: this example processes only one instance to illustrate
the number-to-text translation. To process all instances, replace
"Select-Object -First 1" with a "Foreach-Object" loop, and use
the iterator variable $_ instead of $instance
#>
# query the property
$rawValue = $instance.DebugInfoType
# translate raw value to friendly text:
$friendlyName = $DebugInfoType_map[[int]$rawValue]
# output value
$friendlyName
Use a switch statement inside a calculated property for Select-Object
<#
this example uses a switch clause to translate raw numeric
values for property "DebugInfoType" to friendly text. The switch
clause is embedded into a calculated property so there is
no need to refer to external variables for translation.
Note: to use other properties than "DebugInfoType", look up the appropriate
translation switch clause for the property you would like to use instead.
#>
#region define calculated property (to be used with Select-Object)
<#
a calculated property is defined by a hashtable with keys "Name" and "Expression"
"Name" defines the name of the property (in this example, it is "DebugInfoType", but you can rename it to anything else)
"Expression" defines a scriptblock that calculates the content of this property
in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
value to its friendly text counterpart:
#>
$DebugInfoType = @{
Name = 'DebugInfoType'
Expression = {
# property is an array, so process all values
$value = $_.DebugInfoType
switch([int]$value)
{
0 {'None'}
1 {'Complete memory dump'}
2 {'Kernel memory dump'}
3 {'Small memory dump'}
default {"$value"}
}
}
}
#endregion define calculated property
# retrieve all instances...
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration |
# ...and output properties "Caption" and "DebugInfoType". The latter is defined
# by the hashtable in $DebugInfoType:
Select-Object -Property Caption, $DebugInfoType
Use the Enum from above to auto-translate the code values
<#
this example translates raw values by means of type conversion
the friendly names are defined as enumeration using the
keyword "enum" (PowerShell 5 or better)
The raw value(s) are translated to friendly text by
simply converting them into the enum type.
Note: to use other properties than "Win32_OSRecoveryConfiguration", look up the appropriate
enum definition for the property you would like to use instead.
#>
#region define enum with value-to-text translation:
Enum EnumDebugInfoType
{
None = 0
Complete_memory_dump = 1
Kernel_memory_dump = 2
Small_memory_dump = 3
}
#endregion define enum
# get one instance:
$instance = Get-CimInstance -Class Win32_OSRecoveryConfiguration | Select-Object -First 1
<#
IMPORTANT: this example processes only one instance to focus on
the number-to-text type conversion.
To process all instances, replace "Select-Object -First 1"
with a "Foreach-Object" loop, and use the iterator variable
$_ instead of $instance
#>
# query the property:
$rawValue = $instance.DebugInfoType
#region using strict type conversion
<#
Note: strict type conversion fails if the raw value is
not defined by the enum. So if the list of allowable values
was extended and the enum does not match the value,
an exception is thrown
#>
# convert the property to the enum **DebugInfoType**
[EnumDebugInfoType]$rawValue
# get a comma-separated string:
[EnumDebugInfoType]$rawValue -join ','
#endregion
#region using operator "-as"
<#
Note: the operator "-as" accepts values not defined
by the enum and returns $null instead of throwing
an exception
#>
$rawValue -as [EnumDebugInfoType]
#endregion
Enums must cover all possible values. If DebugInfoType returns a value that is not defined in the enum, an exception occurs. The exception reports the value that was missing in the enum. To fix, add the missing value to the enum.
Description
Textual description of the current object.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, Description
ExpandedDebugFilePath
Expanded version of the DebugFilePath property.
Example: “C:\Windows\Memory.dmp”
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, ExpandedDebugFilePath
ExpandedMiniDumpDirectory
Expanded version of the MiniDumpDirectory property.
Example: “C:\Windows\MiniDump”
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, ExpandedMiniDumpDirectory
KernelDumpOnly
Only kernel debug information will be written to the debug log file. If TRUE, then only the state of the kernel is written to a file in the event of a system failure. If FALSE, the system will try to log the state of the memory, and any devices that can provide information about the system when it failed.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, KernelDumpOnly
MiniDumpDirectory
Directory where small memory dump files will be recorded and accumulated.
Example: “%systemRoot%\MiniDump”
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, MiniDumpDirectory
Name
KEY PROPERTY STRING MAX 256 CHAR
Identifying name for this instance of the Win32_OSRecoveryConfiguration class.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name
OverwriteExistingDebugFile
New debug file will overwrite an existing one.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, OverwriteExistingDebugFile
SendAdminAlert
Alert message will be sent to the system administrator in the event of an operating system failure.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, SendAdminAlert
SettingID
Identifier by which the current object is known.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, SettingID
WriteDebugInfo
Debugging information is to be written to a log file.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, WriteDebugInfo
WriteToSystemLog
Events will be written to a system log.
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | Select-Object -Property Name, WriteToSystemLog

Get-CimInstance -ClassName Win32_OSRecoveryConfiguration -KeyOnly
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 = 'AutoReboot',
'Caption',
'DebugFilePath',
'DebugInfoType',
'Description',
'ExpandedDebugFilePath',
'ExpandedMiniDumpDirectory',
'KernelDumpOnly',
'MiniDumpDirectory',
'Name',
'OverwriteExistingDebugFile',
'SendAdminAlert',
'SettingID',
'WriteDebugInfo',
'WriteToSystemLog'
Get-CimInstance -ClassName Win32_OSRecoveryConfiguration | 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_OSRecoveryConfiguration -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_OSRecoveryConfiguration -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 SendAdminAlert, DebugFilePath, AutoReboot, Caption FROM Win32_OSRecoveryConfiguration 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 SendAdminAlert, DebugFilePath, AutoReboot, Caption FROM Win32_OSRecoveryConfiguration WHERE Caption LIKE 'a%'" | Select-Object -Property SendAdminAlert, DebugFilePath, AutoReboot, Caption
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_OSRecoveryConfiguration -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_OSRecoveryConfiguration -CimSession $session
# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session
$result
