Minecraft launcher (32bit) process is still running after closing minecraft launcher

As I close Minecraft launcher, it still keeps lagging PC and there are some background processes running that can be seen in Windows Task manager.

 

I am unable to produce launcher log files, as they simply do not generate.

Launcher build version:

Launcher
