On my Windows 10 machine, I've installed a Ubuntu system (as a Trusted Microsoft Store app). When I open that window and type help, these are the first lines I see:

GNU bash, version 4.3.48(1)-release (x86_64-pc-linux-gnu)

The results of uname -a are the following:

Linux DOMINIQUEDS 4.4.0-43-Microsoft #1-Microsoft Wed Dec 31 14:42:53 PST 2014 x86_64 x86_64 x86_64 GNU/Linux

In that Ubuntu window, I have lots of interesting Linux/UNIX features, like find, grep, ..., but now I would like to do some process handling (ps -ef, kill -9), and this seems not to work:

When opening Windows task manager, I see ±100 processes running.

When I run ps -ef, (even after having opened the Ubuntu window as administrator), I only see three processes:

DominiqueDS@DOMINIQUEDS:~$ ps -ef
UID PID PPID C STIME TTY TIME CMD
root 1 0 0 17:14 ? 00:00:00 /init
Dominiq+ 2 1 0 17:14 tty1 00:00:00 -bash
Dominiq+ 18 2 0 17:19 tty1 00:00:00 ps -ef

Does anybody know how I can make ps -ef and kill -9 work in this Ubuntu window on my Windows-10 machine?

Thanks in advance

Well you can't.
WSL Bash in Windows 10 runs in a kind of sandbox, and has no access to windows processes.
