Difference between [Setupparams] and [GuiRunOnce]?

[druiddk]

Can someone please explain the difference between [setupparams] and [GuiRunOnce]?

I have setup regtweaks to be run using setupparams and my applications to be installed during GUIRunOnce, but is this right? and if so, why?

Thank you in advance! :-)

[setupparams] launches its commands immediately after Setup completes. GuiRunOnce launches its command(s) upon the first logon. The latter is good for installing s/w, the former... well, I just don't use it

[setupParams] launches it's script at T-9 during setup, and is good for launching applications and registry entries because at T-9, the OS files have been completely installed - the registry is still in default user mode and the registry needs to be built, but otherwise the system is installed. This can sometimes be the best time to install Windows non-critical updates (like the .net framework and Windows Media player, etc.).

[GuiRunOnce] launches the contents of it's script after a user first logs on, after Windows setup has completed and restarted the machine one last time. This method is sometimes necessary for applications that will not (or should not be) installed during the Windows setup process itself.

I'm partial to using a script that is called in [setupParams] to enter default user registry settings, and entering the registry values for all of my applications to be installed into the RunOnce section of the registry.
