How to install Windows 11 on a Windows 10 computer without losing data?

Copper Contributor

I'm currently running Windows 10 on my computer and I'm interested in upgrading to Windows 11. I've heard a lot of great things about the new features and improvements, and I believe it could be a valuable upgrade for my system. However, I'm not entirely sure where to start with the installation process. Could someone please guide me through the steps to successfully install Windows 11 on a  Windows 10 computer without losing data?


Specifically, I would like to know what prerequisites I need to check before initiating the upgrade. Are there any specific hardware or software requirements I need to be aware of? Additionally, what steps should I follow to ensure that my data and applications are safely transferred during the upgrade process?
