How can ObjectCreate IE with Inprivate ?
Browser = ObjectCreate("InternetExplorer.Application")
browser.navigate(url)
Don't think it can be done with COM. You could Run the shell with -inprivate parameter, or possibly Open the ie object then send a postmessage to the window to enable inprivate.
For some versions of IE and Windows there is a registry setting that will enable 'inprivate' by default. The problem would seem to be sorting out where the setting resides in the registry on a system with a given version combination.
