How to hide "This PC" item in filedialog?

Hi there,

  I am new for Windows Azure. I setup a windows 2012 remote desktop service in Windows Azure recently. And publish applications Paint and WordPad. Everything works fine.

The only thing is the Azure VM resources --This PC shows up when I select menu File-->Save as. I don't want users save anything on Azure VM. Let user save file on remote desktop client's machine only.

Is it possible?

Thanks.
