Hi @Nadimuddin J Shaikh ,

The Get-ItemProperty cmdlet can check registry values for you. To create the value if not found, you can try something like this

$KeyPath = "HKCU:\Registry\Key\Path"  
$ValueName = "name"  
$ValueData = "data"  
try{  
    Get-ItemProperty -Path $KeyPath -Name $valueName -ErrorAction Stop  
}  
catch [System.Management.Automation.ItemNotFoundException] {  
    New-Item -Path $KeyPath -Force  
    New-ItemProperty -Path $KeyPath -Name $ValueName -Value $ValueData -Force  
}  
catch {  
    New-ItemProperty -Path $KeyPath -Name $ValueName -Value $ValueData -Type String -Force  
}
