clone Windows OS

When should you transfer your Windows installation to a new hard disk or solid-state drive? It is preferable to create a Windows OS copy to a different hard drive - HDD or SSD - after you have just finished installing the Windows OS and numerous drivers, along with other often used software.

Alternatively, the capacity of the current system disk will be exhausted after some time of use, resulting in a gradual decline in performance. To increase the computer's overall performance and running speed, you may need to copy Windows OS to a new HDD/SSD with greater capacity at that time.

So, the question is, how do you transfer Windows to a fresh disk? You may trust some disk copy software to accomplish your goal effectively. You can easily transfer your Windows installation to a new hard drive without first reinstalling or backing it up.

How come you copy Windows to an external drive?

Let's say that after a long period of use, your disk has become old and weak, and perhaps it lacks enough storage space, causing your computer to perform slowly. Or your hard drive intermittently becomes unresponsive. You may be fed up with Windows and want to clone it to an external hard drive.

Also, after getting a new computer, you can clone the old computer to avoid reinstalling everything. Due to data security reasons, a clone from the system drive to an external device is required. Here are the top three justifications:

1. Replace or upgrade the old disk.

Making a clone of the smaller disk onto the larger one will duplicate all the data on the smaller disk, giving you access to greater storage space. Cloning a hard disk to an SSD is preferable, but computer speed is paramount. An SSD, it is stated, can offer ten times the speed of a regular HDD. If there are issues with the system drive, you can also clone it to a new drive for replacement to avoid data loss.

2. Move Windows OS to another computer.

If get a new machine and don't want to reconfigure the system settings and install the programs, clone the old computer is a good choice. It can help you use the new computer just as the old one without wasting too much time to reinstall everything. For some business users, it's really wonderful to move the Windows OS to multiple machines in this way.

3. Clone Windows OS to external drive as backup

There would be unexpected issues happen to the system drive. A backup is always necessary. A bootable clone of Windows OS can help you reduce the downtime in case the old system drive failed. You can just boot from the cloned drive directly and continue the work.
