Need script for auto locking vista..

ive bypassed the log in while still keeping pasword protected. i need ascript that i can run on login to lock my computer.

and if your wondering the point its so my programs load quicker at start up.. and my itunes alarm works auto without havin to be logged in..

i could also use help with rtc.. i cant seem to find it on my comp.. never mind tell it to turn on.. im on an acer aspire 5720..

all help appreciated..

and as you can tell i have no idea wot im doing so i need you to tlk in a language i understand =D..

no worrys i found a solution..

i created a shortcut for lock and placed it in the startup programs..

so it now logs in.. locks itself.. loads all my start up programs..

and runs and plays itunes thanks to a little nifty script and task sheduler..

i would still like help getting my computer to auto boot using my bios and real time clock..

thanks..
