Can I hide the smiley in Visual Studio 2015 final? -

in visual studio 2015 rc, there feedback smiley in upper right of main window.

unfortunately, still there in final release of visual studio 2015:

i've searched through options , settings , found no way hide smiley.

my question:

any option or other (registry etc.) hack remove smiley?

update 2015-12-01:

yesterday update 1 visual studio released.

while still find no option hide smiley, @ least provided less distracting icon it:

edit:

visual studio 2015 update 1 changes feedback icon understated black , white one no more smiley! it's not mentioned in release notes.

original answer:

as in ops answer, icon specified in registry key:

hkey_current_user\software\microsoft\visualstudio\14.0_config\mainwindowframecontrols{f66fbc48-9ae4-41dc-b1af-0d64f0f54a07}

if delete key, visual studio recreates it, if invalidate "package" value of registry key , restart visual studio smiley icon gone:

however, when install visual studio update (eg ssdt, resharper) installer restores package value, , smiley back. have created registry file run when smiley reappears:

windows registry editor version 5.00  [hkey_current_user\software\microsoft\visualstudio\14.0_config\mainwindowframecontrols\{f66fbc48-9ae4-41dc-b1af-0d64f0f54a07}] @="feedback button" "package"="{00000000-aa51-43b1-97ee-509a33b681f3}" "displayname"="#1001" "viewfactory"="{060eab95-139e-407d-bedc-cc2b7a9b39d4}" "viewid"=dword:00000064 "alignment"="titlebarright" "sort"=dword:00000064 "fullscreenalignment"="menubarright" "fullscreensort"=dword:00000064 

this doesn't seem affect startup time or stability, there no guarantees, registry changes bad mmm, etc.
