MS Office 2007 Enterprise or Blue will work fine and the download file includes the software key. I have used this to make jobsite laptops that sometimes get trashed/stolen so I don;t want to waste $$ on real MS Office purchase. It works and does not report to momma MS that its a hacked version.

DL and burn it to a CD and then back up all your MS Word/Excel, etc files to CD and then install on the new drive..

Of course the other way would be to buy another HDD and install it and use Drive Pro or the like to mirror the old drive to the new. It may not transfer every program so DL as above and prep for the worst.
