Use Student download to "upgrade" new laptop?

Can an .iso of the Win 7 Student download be used to "upgrade" a new laptop with the same version of Win 7, thus getting rid of unwanted programs? In other words, do a clean install using the .iso on DVD, then using the registration key from the new Win 7 laptop?

Assuming it will work, how much problem is there likely to be with drivers?

Thanks much!

If I'mreading it right you have win7 on your laptop and you want to format the drive and put win7 back on? That'll work. As far as drivers are concerned, if you already have 7 installed you would know what drivers did or didn't get installed already
