Should I Clean Install Windows 11

Windows 11 involves enhanced touchscreen interactions, improved multi-monitor support, and multiple desktops on a single monitor. In addition, it also comes with UI improvements, including a new Windows setup screen, a redesigned Settings app, and new icons. If you want to experience the unique features of Windows 11, you can do a clean installation.

A clean installation of Windows 11 is wiping the hard drive and applying a copy of the operating system (OS) to configure a laptop or desktop computer. You can benefit from doing a clean installation of Windows 11.

  • It can help solve issues with an existing setup. For example, a clean installation can help fix memory, shutdown, apps, startup, stability, and performance issues.
  • It can also improve battery life and is an excellent solution to eliminate viruses and other types of malware.
  • It would be the preferred choice to upgrade from an older version while minimizing the chances of any issues during and after the process.

Preparations for Clean Installation of Windows 11

Create backup

A clean installation will remove everything on the target drive. Therefore, creating a backup of your computer is necessary to prevent data loss. On Windows 10/11, you can choose from several backup solutions, but the most effective and reliable way is to use third-party backup software to help create a system image of your computer. Under such circumstances, professional system backup software - EaseUS Todo Backup, comes to help.
