If you constantly see an error message that you can't get rid offor example, from a piece of software that didn't uninstall properly and continues to give errors on startupyou can disable it from displaying on startup.

Run the Registry Editor and go toHKEY_LOCAL MACHINE\SYSTEM\CurrentControlSet\Control\Windows. (Thiskey holds a variety of Windows system settings, such as the location of your systemdirectory.)

Create a new DWORD called NoPopupsOnBoot and give it a value of 1. Exit the Registry and reboot for the setting to take effect. To disable it, either delete the DWORD value or give it a value of 0.
