WinSize2 is a free tool that lets you readjust the size and location of the windows you have on-screen (in the foreground). WinSize2 has the advantage of being able to even adjust those windows that, due to their characteristics, can`t normally be modified.
It also includes the option to modify the texts of the windows. If you want to take screenshots where various windows appear, WinSize2 is a good tool because it makes this task easier. However, it could be a difficult to use unless you master the keyboard. It works among other shortcuts with CTRL + ALT + 1 y CTRL + ALT + 2.
