How to exit full screen in VMWare Fusion 7

You cannot view the windows desktop as the "Desktop" in Unity (As @mankoff said, you can open it as a folder). The intention of Unity is to Run Windows apps "side by side" with Mac apps. This means the Mac desktop is the desktop.

I remember there was an option to "Show taskbar in unity" in a older version. Unable to find it in version 3 (did not look for long, anyway I think this is not very useful)

BTW, the way I use VMWare is only for application installs. All my data still stays on my mac (in a special folder if required) but not inside the VM. Helps me back them up, email them if required (even when the VM is suspended). So I never felt a need to see the desktop.

As the auto-login or password is in Windows, and Windows doesn't know if it is booted via BootCamp or VMWare, I don't think you can do this from the Windows side.

It doesn't seem likely, but perhaps you can set it to always require password, but then use AppleScript and VMWare, or Automator GUI Scripting, to enter the password for you.
