More memory and/or a faster processor certainly would speed things up. The main question is how long would it take to complete the compilation for what would be an average sized amount of code for you. That would be a concern with an IDE or command-line. The compilation stage is likely going to be the only major bottleneck with that PC. It also supports rectangular edit and multi-line identical edit, as well as plug ins that can format code for you. N++ is arguable better for small things as its faster and supports macros which VS removed for some unholy reason. Are you doing big projects/real stuff or homework? All you need for homework is n++ & any compiler. Notepad++ and a compiler works great for me. You can also do many other clever things.

Use a lighter weight security suite & a hardware firewall if you can. I suspect that vs2019 will run smoothly on it (it may be slow to start up, though) if it were clean. That said, do you have solid windows sysadmin skills? Gut the startup crap with ccleaner, kill all the not needed services and background processes and give it a full bore gamer's rig cleanup and speedup. That computer could have functioned as the universitie's entire server room when I was in college if it had a network card bank plugged into it. You have a glorified word processor, and it struggles to run on 2 cpus each doing billions of operations per second with billions of bytes of ram available. Vs code is lighter than full vs and may suit you.
