Code:
Function CheckAndSetRegValue($RegPath, $RegValue, $RegData, $RegType)
  
	$ReturnValue = ReadValue($RegPath, $RegValue)
  
	If ($ReturnValue = $RegData)
		? "Registry value already applied"
	Else
		WriteValue($RegPath, $RegValue, $RegData, $RegType)
		? "Registry value is being set for: "
	EndIf
	
EndFunction

CheckAndSetRegValue($PCSoftware + "\Policies\Mozilla\Firefox", "OverrideFirstRunPage", "", "REG_SZ")


I want the data field of the Registry Value OverrideFirstRunPage to be empty/blank/null. However, I have to put a space in between the apostrophes, otherwise the registry entry is not added. Is there some way to get Kixtart to create a registry value with no data.
