I'm running Vista P2 and have started to experience a number of niggling problems which don't seem to have a straightforward resolution. I carry out all the recommended maintenance activities including daily scanning for malware. And I don't hack around. So I'm not sure what it is that I could be doing wrong.
Anyway, the latest position is that I have managed to enable Windows Live Messenger in msconfig>Startup. If I click on the Startup menu in msconfig first, Normal startup is shown as checked under the General tab. However when I open msconfig after a reboot Selective startup is shown as checked under the General tab even if I choose Normal startup from Safe Boot. Is there a way to check what start up mode Windows has used to reboot? Germ-x said that Selective startup doesn't affect the operation of Windows so perhaps I shouldn't worry unduly.
