Using PowerShell

$regPath = "HKCU:\Software\Microsoft\Windows\CurrentVersion\RunOnce"
$regKey = "RunScript"
$regValue = "c:\setup\script.cmd"

IF(!(Test-Path $regPath))

{

New-Item -Path $regPath -Force | Out-Null

New-ItemProperty -Path $regPath -Name $regKey -Value $regValue -PropertyType STRING -Force | Out-Null}

ELSE {

New-ItemProperty -Path $regPath -Name $regKey -Value $regValue -PropertyType STRING -Force | Out-Null}

 

Using PowerShell App Deployment Toolkit

[scriptblock]$HKCURegistrySettings = {
Set-RegistryKey -Key 'HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce' -Name 'RunScript' -Value '"c:\setup\script.cmd"'-Type String -ContinueOnError:$True
}
Invoke-HKCURegistrySettingsForAllUsers -RegistrySettings $HKCURegistrySettings

 

Using C# in Visual Studio

using Microsoft.Win32; //used by Registry

namespace PlayingAround
{
class WriteReg
{
public static void Main(string[] args)
{
// define variables
const string userRoot = "HKEY_CURRENT_USER";
const string subkey = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunOnce";
const string keyName = userRoot + "\\" + subkey;

// set registry key
Registry.SetValue(keyName, "RunScript", "C:\\setup\\script.cmd", RegistryValueKind.String);

}
}
}

 

Using AutoIt in SciTE-Lite

WriteReg()

Func WriteReg()
  ; Write key
  RegWrite("HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce", "RunScript", "REG_SZ", "C:\setup\script.cmd")
