Not really, but W10 by default loads a lot of apps and services which you don't need, but use a lot of RAM (hibernation, file index the worst). But yes, in very old sistems it's better to use Linux. Q4OS is a good choice for Windows user, with an UI very similar to W7 and it has a own installer, so you don't need to make an CD/Pendrive with an ISO, You can download the setup and run it like any other app and select if you use only the Distro or in dualboot with Windows.
