QTranslate is a free translator for Windows (Windows 8/7/Vista/XP/2008 Server/2003 Server). With this small utility, you simply select the text you want to translate and then press hot key (Ctrl+Q to show translation in the popup window or Double Ctrl click to show the translation in the main window). The program also has the ability to speak text (Ctrl+E) and perform a dictionary search (Ctrl+W). Also, you can open the main window and type text manually.
Note! The program translates a text by using online translation services, so you need an Internet connection.
