: WIN98 - pressing CtlAltDel even just after startup shows about 20 (yes twenty) applics running, mostly unnecessary. This hinders troubleshooting other problems since I have to "End Task" ech individually. None of these running apps seem to be in Startup Group - how do I stop them starting every time the PC is started? Repeat - they are not in the startup folder - HELP!
