What did you think "1-license" meant?
Be aware there you can UPGRADE any legal XP/Vista/W7 computer for $40 (until Jan 31st 2013) to Windows 8 PRO.
If you have a 32-bit copy of Windows you must upgrade to the 32-bit copy of W8 Pro. Same for 64-bit.
You can only transfer applications if you have Windows 7http://windows.microsoft.com/en-CA/windows/buy
