5 Best Lightweight Operating Systems for Old PCs and Laptops in 2024

If you have an older, slower PC or laptop, switching to a lightweight operating system can give it new life and improved performance. While Windows is the most popular OS, it can be too resource-heavy for the old hardware. Luckily, there are several excellent lightweight OS alternatives available in 2024 that are ideal for basic tasks like web browsing, productivity, and streaming on older machines.
