Why clone hard drive in Windows 10/11?

Cloning a hard drive is the process of copying all of the contents of one disk to another to create a full 1-to-1 clone of the previous hard drive. And everything on the cloned hard drive, including the operating system and loaded apps, will load and operate as they did on the original disk, eliminating the need to reinstall the operating system and other programs. The reasons for needing to clone a hard disk in Windows 11/10/8/7 are adequately explained here:

▶ Upgrade your current small old hard drive with a bigger new hard disk to get more space.
▶ Replace the failing hard drive with a good one to avoid data loss caused by disk failure someday.
▶ Transfer all data from one disk to another effectively for a handy backup rather than copying the file by file manually.
