This 50 MB operating system can resurrect your old PC

I have a decade-old Dell Inspiron laptop with a 2nd-gen Intel Core i3 processor, 4 GB RAM, and an integrated Intel HD GPU. It came with Windows 7 out of the box and was eventually upgraded to Windows 10. However, after 13 years, it’s not the most enthusiastic laptop, and getting anything done on it seems like a task in itself.
