Upgrade is switching from an old operating system to the latest operating system. During the upgrade process, all files, programs, and settings will be preserved. On the other hand, a fresh installation wipes the drive and installs Windows 11 from scratch.
Upgrading is easy with Windows 11 Installation Assistant. You won't lose any files and there's no need to format your hard drive. If something goes wrong with the upgrade, you can even revert to a previous OS version. The only downside to upgrading is that Windows 11 tries and keeps all your files. This means useless and unused files are also left behind. This can lead to confusion and the new operating system won't run smoothly.
A clean install allows you to install everything from scratch. You can even get a clean registry. It eliminates all incompatible programs and helps resolve any issues or errors. The only drawback is that you need to back up your files before installing Windows 11.
Now that you know the difference between an upgrade and a clean installation, you can make the right choice. Decide where your priorities are, what is more important to you, and then choose accordingly.
