My mom has a laptop from around 2011 that currently runs Windows 7. Since Windows 7 is no longer supported and is unsafe to use online, I'd like to install a beginner-friendly Linux-based system instead. She mainly needs a web browser, with perhaps LibreOffice for basic documents. The laptop has about 4 GB of RAM and integrated Intel graphics. Which option would be lightweight, reasonably secure, and easy for someone who has used Windows since Windows 98?

Xubuntu is another good beginner-friendly option. It has a lightweight Xfce desktop without feeling too stripped down. Puppy Linux, antiX, and MX Linux can run on weaker hardware too, but some of them may require more adjustment and may not be as comfortable for a new user.
The distribution itself isn’t what determines performance as much as the desktop environment and the applications running on it. Choose a well-maintained distribution and pair it with a lightweight desktop such as Xfce, LXQt, or MATE. Security updates and an actively supported browser matter more than finding the absolute smallest system.
Linux Mint with the Xfce desktop would be a strong choice. It’s fairly light, easy to use, and familiar enough for someone coming from Windows. With 4 GB of RAM, it should be comfortable for basic browsing and office work.
You might also consider ChromeOS Flex. For someone who only needs a browser and wants something difficult to misconfigure, it can be simpler than a traditional Linux desktop. Just check whether the specific laptop model is officially supported, since older hardware can have compatibility issues.

The laptop has around 4 GB of RAM and integrated Intel graphics, so I’m mainly looking for something that won’t feel sluggish.
