If you have the Office disc it can be loaded on to 3 computrers so if the previous laptop was the first or second time you'd used the Office disc then yes you can. Hope this helps!
Ah, the only way to do that would be to put them all on disc, USB stick or external harddrive then transfer them over. Or, if you have an email adress like hotmail or yahoo then you could email them to yourself and open them on the new computer.
The perfect time to buy an external hard drive to back up all your files.
Easy to transfer them between pcs and every pc user should have a reliable back up.
