How can I access unselectable text from windows?

Question

How can I access/copy unselectable text from windows (in Windows 7)?

For example, when a warning/error/info popup box (or window) appear, is there a way to access the text of it (when the text is unselectable)?

I'm wondering if there's a utility or method to possibly access such, sort of like a "DOM Inspector" for a web browser.

Note:

The text is in the form of a label, and not any sort of textbox or inputtable text element.

Answer 1

If it is a standard dialog box, you can press Ctrl+C to copy the title, contents, and the available buttons (OK, Cancel).

Answer 2

Try Password Viewer

Drag and drop where you want it to reveal text.
