You can transfer operating system from one computer to another without reinstalling Windows from scratch. This guide covers two methods: disk cloning and system backup and restore. After the transfer, a universal restore may be required to resolve hardware compatibility issues.

When replacing an old PC, you can transfer your existing Windows environment to the new one instead of reinstalling Windows and applications. This operation can preserve your installed programs, system settings, and personal files.

However, OS transfer is different from simply copying files. You should take hardware compatibility problems and Windows activation issues into consideration.

How to Transfer Operating System from One Computer to Another

To transfer Windows from a PC to another PC, try two methods:

  • Disk cloning: Copies everything, including system settings, apps, registry keys, and files, from the old computer to the new one. It offers a direct old-PC-to-new-PC migration.
  • Backup & restore: Transfers a system image to a new computer.

The professional Windows backup software, MiniTool ShadowMaker, can perform these two tasks. It offers powerful features such as Clone Disk and Backup, to clone a hard drive and back up your disks/partitions/files/systems.

Additionally, its Universal Restore feature can also help resolve boot problems caused by different hardware.

Next, let’s explore how to clone one computer to another.

MiniTool ShadowMaker is a disk image tool that can backup files, folders, systems, and disks/partitions within a few clicks and restore your PC to its previous state on Windows 11/10/8/7.
