|"Usually" the drive will arrive with a cd that allows you clone (copy) your current disk (entire contents) to the new drive.|
If it doen't come with the disk then "usually" you can go to the website for the your new drive, download, burn to cd/dvd their utility. Then run it as directed in the instructions.
If you decide to build a totally new installation windows... you " may" have to re-activate, but not definitely so. I have changed drives and rebuilt OS etc. anew, sometimes had to re-activate, and sometimes not.
I usually do the activation initially on-line, and if it doesn't go through OK then use the telephone route.
Regardless of how you go about it all... First safeguard all your personal files etc. - off the current drive; typically to dvd. Check the copies are ok as well. Then do the drive change...
