Nothing is more infuriating than software that will, without asking you, modify the registry to launch when you start the Windows.
If you have a small config or a family computer, after a year your system will take 20 minutes before launching so it will be saturated!
To avoid this kind of inconvenience (and avoid using the command msconfig> Startup every week), install StartupEye.
StartupEye is a small program that monitors and relieves systems of applications that run automatically at startup. This software will notify you as soon as a software tries to find a place in the list of those that launch at startup. StartupEye notifies you and gives you the choice to prevent this operation.
This allows you to avoid regularly modifying the startup options from Msconfig to deactivate unnecessary software or adding executions inadvertently.
The utility works under XP, Vista, 7 and Windows Server 2003 & 2008 and it can be downloaded here.
