How to Copy & Clone Hard Disk to New Hard Drive in Windows 10/8/7?

When do we need to clone disk?

At some point, you intend to upgrade hard drive to an SSD or a new hard drive, and to transfer Operating System hard drive is especially a headache. On the other hand, if you fresh install the OS on the new drive, you must reinstall all the software and set up your personal configurations once again. What’s worse, if you have not backed up activation information of your purchased software, you may have to reactivate them again. It will be a disaster if you lose the activation keys. Applications installed on the old drive will fail to run on new one because of the lack of old Windows registry. In this case, the best way to solve the problem is to clone the boot disk to your new drive without reinstalling Windows or installed applications.
