Several days before, I bought a new computer, as I had always heard from people that the windows 7 system crushes sometimes, so I decided to make a copy of my windows 7 system. But I didn't know how to
clone windows 7 system, so I asked one of my friends for help who has much more experiences on computer than me. And he suggested me to use Easeus todo backup software. I tried and I successfully cloned my system. I was very happy that the software is so easy to operate, I post this on this forum hoping that can help more people.
