BAH!!
Captus (the software I used for screencapturing) just stated that my evaluation period has ended, which apparently was only total of 29 screen captures...

So screen capturing is going to be in a ice untill I can think of how to replace the captus. And yes, I know about Print Screen button in windows, it's just so damn slow to:
1) Capture the screen
2) Paste the capture to Paint
3) Select the actual area I want to be saved and copy it
4) Open new file and paste the image to it
5) Save and close the file
Rinse and repeat that around 30 times with different image names, and you know it's getting frustrating. Especially since the new image in Paint creates image area with fixed size, which will get changed if the picture does not fit to the area but only if the actual image is bigger, not when it's smaller. So result with small pictures being pasted is huge area of white, which still exists after saving.
So, anyone knows any good and
free software for this purpose? It should be able to save files in png format...
