if ie10 is what came with the os out of the box i dont think it can be uninstalled but if your os came with like ie9 and you upgraded it to ie10 you remove it from the installed update page if i rember right..... go to windows update then to installed updates scroll to the ie10 update package then remove. but as i said if its the one that came natively built in the OS i dont think it can be removed.
