Is there an elementary os keyboard equivalent to windows ctlr+alt+del that would launch a task manager, process list, ability to set affinity, priority, kill a proces,monitor memory and cpu loads, + performance. Or which ubuntu/software task manager can I install that is not going to break anything?

Are you comfortable to use terminal (CLI)?– RavanNov 14, 2015 at 8:10

Fabby - glad you pointed out this oversight on my part. I ticked all three responses, but it seems only one will stick. All were helpful. Any one of the three options work, and I have installed all three. I love efficiency and htop seems to have won that title, but for gui system monitor seems best. YMMV– jmarkusNov 15, 2015 at 19:23

elementary OS doesn't ship with a system monitor by default. I would recommend installing GNOME System Monitor from Software Center:

sorry, @Daniel why are you avoiding to give terminal command
sudo apt-get install gnome-system-monitor. Just curious to know :)– RavanNov 14, 2015 at 8:15 -
4Hey @Ravan this kind of discussion is not really appropriate for comments on an answer; it would be better suited to meta. But to answer your question, I don't think it's generally a good idea to condition new users to enter Terminal commands from the Internet. In fact, Terminal explicitly warns against it when you try. This is how a lot of people break their installs. Terminal is a developer's tool and isn't required to perform tasks like installing new apps. Nov 14, 2015 at 19:36

thank you =) @DanielFore, I will post on meta, please answer :) I understand your point.– RavanNov 15, 2015 at 1:11

I request you please don't DV for CLI answers, (regarding htop), I clearly mentioned that is CLI.– RavanNov 15, 2015 at 1:14
One of the GUI-based task manager is LXTask
Lightweight, simple
Monitors processes
Can kill processes
Real GUI
Installation:
- From Software Center
Or
From terminal:(If you are comfortable with terminal)
sudo apt-get install lxtask

Installed both, and they seem pretty good. I would like a keystroke combo to launch one of them - should the plank become unresponsive. (It has due to high cpu usage of gala, but I think I have that solved now) Is there a way to assign ctrl+alt+del to launching Gnome system monitor, or lxtask?– jmarkusNov 14, 2015 at 15:40

Worked great for creating another shortcut for the terminal. But for sytem monitor the terminal is saying this ** (gnome-system-monitor:6378): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-GKMKspk4te: Connection refused ** (gnome-system-monitor:6378): WARNING **: SELinux was found but is not enabled.– jmarkusNov 14, 2015 at 16:27
If you want to use CLI, you can use htop.
Installation:
- From Software Center
Or
From terminal:
sudo apt-get install htop
To start htop you have to run htop in terminal.
It can list all the processes with CPU/RAM usage, Overall CPU/RAM usage and more. It can also kill a process. You have to use up and down arrow keys to navigate.

If your computer is being slowed down by something, and you need a shortcut to get to it, you can switch to a terminal with
Ctrl+Alt+F1(or F1-F6), and switch back withCtrl+Alt+F7(which is the terminal that the OS's visuals/GUI, the X Window System server, uses).– Ben JOct 20, 2018 at 3:52
