I have decided to carry out a clean reinstall on a PC which has developed an issue which appears to be registry-related. The PC resets itself after every reboot, for example whatever background I select for the desktop, it always reverts to Windows own background. I would like to keep all data, files programs and apps, however I'm aware that a clean reinstall will not allow me to do that. I have made a system backup on an external drive as well as a disc backup on another external drive. I used Aomei Backupper to create the backups. On going into the backups, they have the extension .adi. What I'm not sure about is the actual process of reinstalling or resetting Windows 10, then restoring data and files from the backup I've made. I'd be grateful for any advice that anyone could provide me with regarding the process.
