Hi everyone, I'm Junior Web Developer who code using windows 10. and I just got front-end project using vue as main framework.

Everything seems to be fine, until lately my pc felt slowing down. Turn out, there is a program that commit (aprox ) 2.5GB from my 8GB of RAM. It is called "nslookup.exe". At first, I just killed the program, and I got my 2.5GB space RAM back and everything just run normally, no crash or anything. Only for 5-10 minutes, the program start to run again for some reason and took the same amount of my space RAM, 2.5GB

I search about it, asked why this program keep running and do nothing useful from what I see. Or maybe I just using it without knowing it, I had no idea about it.

Here what it look:

I planned to reinstall my windows 10 if this issue keep occurred. Before doing so, is there any clue, steps or guidance in some article out there that can help?

Any help is appreciated. :)

And sorry for my english, it is not my main language.
