Unfortunately the search engine on this site isn't the best and the fact that most thread titles are "I'm new, please help" means it's almost impossible to find information discussed previously.

So I'll give you the gist of it. If you want to speed up when you log on you will need to change XP to use the classic style logon. Else you can press Ctrl+Alt+Del whilst it's logging on and this seems to make LS appear more quickly. There is no fix for this bug.
