there is a file that u can write some file names in it and windows will delete those files next time it restarts.. i think it is sometimes used by setup programs..

the problem is i forgot that file name because i read it somewhere along time ago.. does anyone know it?? i will be grateful if u tell me

if not, then how can this be done? i mean make windows delete some unneccessary files next time it resarts.. i have thought of adding a bacth file to the start up.. but it would be noisy, i would appreciate any ideas..
