I would like to (if possible) just get rid of windows 7 and start using vista again.

I do not have a Vista CD as my Laptop came with it built in.

if you have the iPhone data plan on your account and
switch the sim to another phone will the internet work
on the other phone as well or not?

I have this program called ultimate cleaner 2007. Its an annoying spyware program that creates pop ups on my computer even when Im offline. I’ve tried removing, searched for it, went through my hard drive and went throuhg add/remove programs list. I found a program to solve the problem but it costs money. Im running spyware docter and that got everything but the ultamite cleaner 2007, can someone please help me?

I have the microsoft office discs that came with Vista would i be able to reinstall them on WIndows 7 without any problem?
