You need to make a windows service so it can run even if the user isn't logged, take a look at this article and for more information read the MSDN..
for the Screenshots:
ScreenCapture sc = new ScreenCapture();
// capture entire screen, and save it to a file
Image img = sc.CaptureScreen();
// display image in a Picture control named imageDisplay
this.imageDisplay.Image = img;
// capture this window, and save it
sc.CaptureWindowToFile(this.Handle,"C:\\temp2.gif",ImageFormat.Gif);

don't you have a C# source for that kind of service, because I don't know VB and this is the first time when I have to create a service... – Victor Dec 29 '12 at 12:01

@Victor If you cannot read VB.NET then simply compile the code to MSIL and have [Reflector](http://www.reflector.net/) display it as C#. Seriously, though, if you know C# then you should be able to read VB.NET without difficulty. – IInspectable Dec 29 '12 at 12:33

I read it, but I am not as good in VB as in C#. I do not often program in VB – Victor Dec 29 '12 at 15:56
