Methods

Win32_PnPDevicePropertyReal64 has no methods.

Properties

Win32_PnPDevicePropertyReal64 returns 5 properties:

'Data','DeviceID','Key','KeyName','Type'

Unless explicitly marked as writeable, all properties are read-only.

Data

REAL64

The property value.

DeviceID

STRING

Identifies the PnP device.

Key

STRING

The value of the Key Name-Value pair that identifies the Data property.

KeyName

STRING

The name of the Key Name-Value pair that identifies the Data property.

Type

UINT32

The type of the Data property.

Type returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

#endregion define hashtable

<#
  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 "Type", 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:
#>
 
$Type = @{
  Name = 'Type'
  Expression = {
    # property is an array, so process all values
    $value = $_.Type)

# ...or dump content of property Type:
$friendlyValues = Get-CimInstance -Class Win32_PnPDevicePropertyReal64 | 
    Select-Object -Property $Type |
    Select-Object -ExpandProperty Type

# output values
$friendlyValues

# output values as comma separated list

Use $Type_map to directly translate raw values from an instance
<# 
  this example uses a hashtable to manually translate raw numeric values

  there is just one instance to work with.

  this example uses a switch clause to translate raw numeric

<#
  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.Type

#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 **Type** 
[EnumType]$rawValue 

# get a comma-separated string:
[EnumType]$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 [EnumType]
#endregion

Enums must cover all possible values. If Type 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.

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 = 'Data',
              'DeviceID',
              'Key',
              'KeyName',
              'Type'

Get-CimInstance -ClassName Win32_PnPDevicePropertyReal64 | 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_PnPDevicePropertyReal64 -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_PnPDevicePropertyReal64 -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 Key, KeyName, DeviceID, Data FROM Win32_PnPDevicePropertyReal64 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 Key, KeyName, DeviceID, Data FROM Win32_PnPDevicePropertyReal64 WHERE Caption LIKE 'a%'" | Select-Object -Property Key, KeyName, DeviceID, Data

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_PnPDevicePropertyReal64 -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_PnPDevicePropertyReal64 -CimSession $session

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

$result

Requirements

To use Win32_PnPDevicePropertyReal64, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

Win32_PnPDevicePropertyReal64 was introduced on clients with Windows 10 [desktop apps only] and on servers with Windows Server 2016.

Namespace

Win32_PnPDevicePropertyReal64 lives in the Namespace Root\CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.

Implementation

Win32_PnPDevicePropertyReal64 is implemented in CIMWin32.dll and defined in Cimwin32.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\Cimwin32.mof
