One thing to consider is switching to Linux. The laptop I am using right now is over 10 years old (Compaq dual core AMD with 2GB RAM with 256GB hard drive) and running Linux Lite 64. I use the Firefox web browser. LibreOffice works well for any writing I need to do. A little slow to boot up, but once up and running she is very workable. Plus it stays updated and I get to decide when to update (unlike Windows 10). Now I'm not going to be doing any video editing on this thing, but for typical day to day use it works just fine.

Something to think about....
