Record your PC using DBox Win Server.

DBox Win Server is a simple tool for recording your PC. By using this tool, you can record your PC to see more about it activities. It is very simple and easy to record your PC with DBox Winserver. This tool also supports UDRec and GGrab.
Although JTG is also a super tool for this job but it is a little overkill. So I think DBox Win Server is the best solution.

How to record using Dbox Win Server:

•  First you need to create a directory on the PC to store your recordings.
• Then Install Dbox Winserver (if you already installed it, you can skip to next step).
• Run Winserver (dboxwinsvr.exe).
• Click the Settings tab and enter your Dbox IP, the port should already be 4000. Set the output directory to  the directory you created above.
• Click the Generally tab and remove the tick from Windows after recording unless you want it to perform the action in the dropdown box once it’s finished.
• Select Use UDrec.
• Click the UDRec tab and select Record only 1 Stream under Audio and Record as MPEG-Streams under Stream File.
• Select Multiplex MPEG Streams after recording. (Keep an eye on your hard drive space though, as you effectively have 2 copies, the muxed and the demuxed. If you can get GGrab to work for you, you can have it only create the mpg file).
• Click Save.

 And you're done!
