So far no error message pop up or crashes when I unplug usb. After I finish with recording for Camtasia. I notice libraries folder is completely change and not show folder. This is look like. I was like.....What did I do? I think this is cause by Registry Easy when I clean up. I did look up the google about libraries folder disappear. I did follow the step. Nothing working. What can I do than their step by step? I did follow this step. http://social.technet.microsoft.com...install-the-default-libraries?forum=w7itproui And it is not going well. Any idea I can do? I know there is other way to use the folder from user folder. But I want libraries folder back.
