My mom has a laptop from around 2011 that currently runs Windows 7. Since Windows 7 is no longer supported and is risky to use online, I'd like to install Linux instead. She has used Windows since Windows 98, so the replacement needs to be simple and reliable. Her main needs are web browsing, Vivaldi, and basic LibreOffice use—nothing particularly demanding. The laptop has about 4 GB of RAM and integrated Intel graphics. Which Linux distribution and desktop environment would offer the best balance of low resource usage, security, and ease of use for her?

The distribution itself usually isn’t what determines how demanding the system is; the desktop environment and enabled services matter more. Fedora, for example, offers several desktop variants, so you can choose a lighter one while still using a well-maintained and security-focused base.
MX Linux, antiX, Puppy Linux, and Lubuntu are all worth considering, but the lightest option isn’t automatically the best choice for a nontechnical user. I’d prioritize a supported system with a straightforward desktop over saving every last bit of memory.
You could also look at Xubuntu. It’s lightweight without feeling too unusual, and it has worked well for older computers used mainly for browsing and email. The familiar desktop layout can make the transition easier for a long-time Windows user.
Linux Mint with the Xfce desktop would be a good starting point. It’s relatively light, familiar for someone coming from Windows, and generally easy to maintain. With 4 GB of RAM, it should handle browsing and basic office work comfortably.
ChromeOS Flex might be worth considering if the laptop is supported. For someone who only needs a browser and wants minimal maintenance, it can be simpler and harder to accidentally misconfigure than a traditional Linux installation.

That makes sense. I’ll compare the lighter desktop options and test one from a live USB before installing it permanently.
