Why Need System Clone in Windows 10?

System clone, also known as system migration, is the process of creating a bootable and intact copy of Windows 10 to another disk. It is quite common among today's computer users, mainly due to the following two scenarios:

  • Low disk space: With time goes by, the free space of a hard disk will become less and less due to the installed apps, temporary files, caches, etc. Sooner or later, you will be warned with low disk space.
  • Poor performance: Computer hardware is updated quickly, an old hard drive that is still functioning may have a hard time keeping up with the demands of new apps and games. Therefore, you may want to replace your system drive with a new SSD to improve performance.

In these cases, many users choose to upgrade hard drive in Windows 10 to a larger drive or an new SSD. But if you don't want to follow the traditional way (install Windows 11 from scratch and migrate the important data over), system clone is the best way to go. It eliminates the need to reinstall Windows 10 and allows you to quickly use the familiar system on the new disk. All the data you need can also be cloned over together.
