if I want to buy a new pc (different spec) and still using the same hard drive from my old computer. It looks like I can make it using the windows 7 native image tool with the use of sysprep?!! I knew product like Arcronis and paragon able to do this, but didn't know windows 7's native tool could achieve this too.... is this true? Here is the article I found but I haven't tested it yet. And if it works, even with Acronis or Paragon, does this break license agreement of OEM and retail license?
