I remember I failed because the variables only existed for the duration of the process. I had a fresh look at this problem today and was thrilled to see a 3rd argument added to the SetEnvironmentVariable<http://msdn.microsoft.com/en-us/library/system.environment.setenvironmentvariable.aspx> method. I wrote a console app with this single line of code: Environment.SetEnvironmentVariable("Foo", string.Format("{0:HHmmss}", DateTime.Now), EnvironmentVariableTarget.User); In a bat file I then called this app followed by a "set f" command. But sadly the Foo value is not present. I tried setting target to Machine, but this requires admin privileges to write to HKLM. Even more sadly it does work either because it seems to write the reg entry but the new value is not immediately picked up by the batch file. Does anyone know of a trick to programmatically set environment variables for use in a bat file? Greg
