SetBinaryValue

Sets the binary data value of a named value.

Sets the binary data value of a named value.

Example

Do not run below example code just to see what happens next. Many methods seriously affect your system. Always make sure you actually understand what the method and the code do.

# define the arguments you want to submit to the method
# remove values that you do not want to submit
# make sure you replace values with meaningful content before running the code
# see section "Parameters" below for a description of each argument.
$arguments = @{
    hDefKey         = [UInt32](12345)  # replace 12345 with a meaningful value
    sSubKeyName     = 'someText'  # replace 'someText' with meaningful text
    sValueName      = 'someText'  # replace 'someText' with meaningful text
    uValue          = [UInt8[]](12345)  # replace 12345 with a meaningful value
}


Invoke-CimMethod -ClassName StdRegProv -Namespace Root/default -MethodName SetBinaryValue -Arguments $arguments

To run this method on one or more remote systems, use New-CimSession:

$ComputerName = 'server12','server14'  # adjust to your server names
$Credential   = Get-Credential         # submit a user account with proper permissions

# define the arguments you want to submit to the method
# remove values that you do not want to submit
# make sure you replace values with meaningful content before running the code
# see section "Parameters" below for a description of each argument.
$arguments = @{
    hDefKey         = [UInt32](12345)  # replace 12345 with a meaningful value
    sSubKeyName     = 'someText'  # replace 'someText' with meaningful text
    sValueName      = 'someText'  # replace 'someText' with meaningful text
    uValue          = [UInt8[]](12345)  # replace 12345 with a meaningful value
}

Syntax

uint32 SetBinaryValue(
  [in] uint32 hDefKey = HKEY_LOCAL_MACHINE,
  [in] string sSubKeyName,
  [in] string sValueName,
  [in] uint8  uValue[]
);

Parameters

Name Type Description
hDefKey UInt32 Optional parameter that specifies the tree that contains the sSubKeyName path. The default value is HKEY_LOCAL_MACHINE (0x80000002). The following trees are defined in Winreg.h:
HKEY_CLASSES_ROOT (0x80000000)
HKEY_CURRENT_USER (0x80000001)
HKEY_LOCAL_MACHINE (0x80000002)
HKEY_USERS (0x80000003)
HKEY_CURRENT_CONFIG (0x80000005)
HKEY_DYN_DATA (0x80000006)
Note that HKEY_DYN_DATA is a valid tree for Windows 95 and Windows 98 computers only.
sSubKeyName String Specifies the key that contains the named value to be set.
sValueName String Specifies the named value whose data value you are setting. You can specify an existing named value (update) or a new named value (create). Specify an empty string to set the data value for the default named value.
uValue UInt8[] Specifies an array of binary data values.

Return Value

Returns a value of type UInt32. Typically, a value of 0 indicates success.

Requirements

To use StdRegProv, 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

StdRegProv was introduced on clients with Windows Vista and on servers with Windows Server 2008.

Namespace

StdRegProv lives in the Namespace Root/default. This is not the default namespace. Use parameter -Namespace root/default with all CIM cmdlets..

Implementation

StdRegProv is implemented in Stdprov.dll and defined in RegEvent.mof. Both files are located in the folder C:\Windows\system32\wbem:

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