Go to: C:\Users\your_user_name\AppData\Roaming\VMware\preferences.ini
Add this line: pref.vmplayer.fullscreen.nobar = "TRUE"
save.

Now you will not see the blue edge of the tool bar in full-screen mode.
To return to normal mode, press “ctrl+alt” to release the control, then press “ctrl+alt+Enter” to regain normal mode.

Ps: I also read someone said that the above line doesn’t work for him, he had to use:
pref.vmplayer.fullscreen.nobar = 1.
However, the “True” version works just fine to me. So I don’t have to bother it at least for now.
