Hello! So my parents' laptop is around 13 years old now and it has 500MB of RAM ( ? ) and an Intel Pentium something something. They're currently running Windows 7 but updates soon stop for Windows 7 and I'm trying to find a new OS for them. They mostly use it for simple things like web browsing and maybe some Office things ( Powerpoint, Excel, Word ). What is the best OS to use on such a laptop?
