An upgrade is a common way of switching from an older Windows operating system (OS) to a new version. All computer settings, programs, files, etc., will be kept during the upgrading process. On the other hand, a clean installation will wipe the hard drive and the current OS and install Windows 11 from scratch.
Just like the proverb goes, "Nobody's perfect." The two options inevitably have merits and demerits.
Advantages of Windows 11 Upgrade
- Users usually perform an in-place upgrade to install Windows 11 on a PC. With the help of the Windows 11 installation assistant, the upgrading process is almost automated.
- You do not need to format your hard drive, reinstall applications, or change Windows settings after the updating because you may keep everything currently on the computer.
- You can revert to the earlier version of the Windows operating system when something goes wrong or if you do not want to keep the current version.
Disadvantages of Windows 11 Upgrade
- Windows 11 attempts to migrate all of the data from the previous version to the new one when upgrading. During the process, Windows 11 also keeps many unused and useless files and other junk files, thus cluttering the new system at the beginning.
- Some programs and drivers not compatible with Windows 11 cannot run properly.
Benefits of Clean Install Windows 11
- A clean installation can allow you to start from scratch, and any bloatware or trial software pre-installed with your system will not be installed. And you can also have a clean Windows registry.
- Clean installation helps you eliminate all incompatible programs because it deletes all the apps. Therefore, you do not need to uninstall these apps manually.
- A clean installation can help resolve some issues because errors and other problems are sporadic.
Drawbacks of Windows 11 Clean Install
- Some data will be removed after a clean installation. You need to back up your files before you perform a clean installation.
- After the clean installation, you still need to personalize your computer.
Since a clean installation of Windows 11 will wipe all data on the hard drive, you should better create a backup of your computer before you start the process. Besides, although Windows 11 upgrade will not delete the content on your PC, a backup is highly recommended in case something goes wrong in the upgrading process. Professional backup software, such as EaseUS Todo Backup, comes to help at this time. You can use it to create a computer backup to avoid data loss.
