Como Formatear Una Laptop E Instalar Windows 10 Desde Cero

I'm using Windows 11, and I have Onedrive set to sync Desktop and Downloads. I don't like this feature, because every time I put a 1 gig file on either folder it instantly starts syncing to my Onedrive, which only has like 1 gig capacity. When I went to one-drive settings and "Choose folder", I tried unchecking Desktop and Downloads, but it says "Can't stop syncing this folder".
