The great thing about Windows is that you can configure just about everything to be precisely the way you want your computer to be. You can choose different themes and colours for your desktop, and you can have different sound effects too. There are also various free hotkey programs around, so that you can program certain key combinations to do exactly what you want them to.
But what about your mouse? Ever wanted to be able to program your mouse so that, for example, the scroll wheel adjusts your speaker volume or the right button opens your browser?
If so, now you can do it. X-Mouse Button Control is what you need. It's a free program for Windows that you can download from http://www.highrez.co.uk/downloads/XMouseButtonControl.htm. It's totally free, and is a 4 MB download. The program runs on Windows XP and above, and automatically adjusts for both 32- and 64-bit installation.
Once installed, click the icon in the system tray to bring up the configuration screen. You can now program your mouse just as you like it.
My thanks to Panzer for this great tip. I've checked out the program with VirusTotal and it appears to be 100% free of viruses and malware.
