I can use windows task manager to enable or disable the startup items. But when I uninstall and reinstall the program, the related startup item re-appears with the same status of enable or disable as that before uninstalling. So, I wonder where does the system store the status information. I try to search the regedit but no results. I mean the status (show in the pic) of the startup items rather than the items themselves. Please do not tell me about the "startup" folders or "HKLM\****\RUN" key.
