Finally, after long time I have recorded my first screencast and uploaded onto TechNet EDGE. The overall experience was good for recording. Since this is my first attempt the audio level is little low. But I managed to record few more screencasts on Native VHD and Boot from VHD efficiently with perfect audio balance.
UPDATE: The video is uploaded with improved audio quality.
The topic I selected is AppLocker: An Overview in Windows 7 and Windows Server 2008 R2.
Here is the link to the screencast. I hope you will enjoy this.
