Hi Freddie-Rayner -
Thanks for the response
It's always a good practice to backup your files before doing any upgrade on the computer though you will not loss any files during the upgrade, it is better to do a backup just in case something happens. As for the RAM, if you turn on a full visual effects then the consumption would be more than typical. Windows 10 and Windows 11 consume the same amount of system resources.
