What are the differences between Run, RunOnce and RunOnceEx?


Recommended Posts


Here's Microsoft's answer :wacko: which makes sense and is info I can use:

The Run key is processed after every logon, either by the Explorer shell, if it is present, or by First Boot Agent (FBA), if a custom shell, Command shell, or Task Manager shell is used. If FBA processes this key, it does so after every logon, not during first boot as it normally would. Typically, this flag is used to load Systray applications, launch services in executables, hide autostart applications, or hide background processes.

1: RunOnce. Default.

The RunOnce key is processed only once, by FBA, after Plug and Play device enumeration and DLL registration processing have completed. The values of this registry key are deleted from the registry after it is processed, so that it will not run again. Typically, this flag is used when a reboot is required, such as for a DLL or OCX registration, or for cleaning up a setup or an uninstall.

2: RunOnceEx.

The RunOnceEx key is processed only once, by the Explorer shell, after the first logon. The values of this registry key are deleted from the registry after it is processed, so that it will not run again. If the Explorer shell is not present, this key is ignored. Typically, this flag is used for a process that runs only once, and that either cannot be run correctly by FBA or requires the system to be fully operational.
