I've done this recently and two things can bite you: 1) Windows Installer WriteEnvironmentStrings doesn't send the broadcast message if there is a pending reboot already. 2) If you want to use it in a windows service ( such as IIS worker pool ) you'll have to take the reboot for it to take effect.

This cmdlet depends on binaries that are present in the directory that we add to "PATH" in the MSI. Since the value of "PATH" does not change (even in a new process), the users have issues running the PowerShell cmdlet. I would expect it to take effect immediately after MSI installation so that any new process have the updated value for "PATH" variable.
