start up types?

not long ago, my pc went away for repairs and when it came back i noticed it was running on a different start up type. And somehow it has changed back, and i would like to know how i change the start up type.

e.g.right now when my pc logs on a box appears in the middle of the screen and u cant get rid of it, but when it came back from being repaired it didnt come up on that start up type.


sorry if this is confusing :S

i need help though

 

Go to start/control panel/user accounts/change the way users log on and off, you can change this around and see which way you like best. ed

 

thanks for that but that isnt what i mean,
when i got it back there was something in the 'run' program that when i typed in brought up the different start up options.
