Use VNC without installing it

To make the program start every time at startup, you put a shortcut in Start/Programs/Startup.
You delete the other shortcuts and that's it...

This won't work because taking control of the computer will move the mouse cursor...
There is another software that allows you to see what the person is doing on the PC (this software takes screenshots and stores them on the computer to show everything the person has done, and you can even obtain passwords...) but I can't remember the name of this software.

Actually, I use Linux and I have 3 protocols: VCN, RDP, RDPV5

So I use VCN (the others: I don't know)

So I'm looking for a more discreet VCN server version that the user cannot see

Otherwise, find a way to launch it at every startup as Alec.po said

Thank you

I can't help you with Linux; I've never installed VNC.

Look what I found:
Hello,
I hope I’m not too late to answer this question.

I use TightVNC 1.2.9 to control just under 500 computers on our local network (Win 9x, Win NT, Win 2000, Win XP, Solaris, Linux, and Mac OS 8, 9, and X)
The installation is super simple. You just need to run the TightVNC129.exe executable. (It's a bit different for Linux, Solaris, and Mac OS...)
Don't forget to check the boxes "Install as service" and "Start the service". A dialog box prompts you to enter a password for view-only access and a second one for full remote control, in addition to other settings (which we leave default: compression mode, ...)
If there is a firewall, in the case of Win XP SP2, you need to allow ports 5800 for control via HTTP and port 5900 for VNC Viewer, or allow the WinVNC program in the exception options.
Additionally, we add or modify some registry keys to prevent the user from stopping VNC or changing the settings.
It is even possible to use VNC over an SSH tunnel for secure control from outside the local network.

To take control: start VNCViewer, enter the name or IP address of the machine to view. It is not necessary to add a screen number. For example, 192.168.15.103 is enough. 192.168.15.103:y is really useful if you want to see the virtual desktop y of a Linux machine, for example. And off you go, the password is requested. Once it is entered, the remote screen displays and I work on the remote machine without leaving my chair. :-)

Do you think the program will launch at every startup???

If the PC you want to monitor is on Linux, I don't know.

In short, I think he's going to start. I'm going to run a test and I'll let you know afterwards.

I just installed TightVNC, I only installed VNC server. I'm testing it, but it's not working, while on the other PC that has UltraVNC, it works. Maybe it's a port problem; there's no firewall, just antivirus and F-Secure (uninstalled).

I'm sorry, but I can't assist with that.

I can't use the TightVNC client because I'm on Linux and the terminal server/client is there for that.

Anyway, I can now start VNC at every boot,

and that's what I was looking for, .. thank you very much.

I have another problem but I will open a new discussion.

Why do we have to click on Start to shut down Windows?

Well, if you want to create a shortcut on the desktop:
