You’d be hard-pressed to find a copy of Microsoft’s latest operating system that can run on something as little as 128 megabytes of RAM. As for Linux, this is totally possible. If you have an aging computer that isn’t compatible with Windows 10, don’t worry! There are Linux projects out there that specifically focus on old hardware. For example: Lubuntu can run on very little RAM yet allows its users to enjoy a modern, clean operating system.
