[HKEY_CURRENT_USER\Software\Microsoft\Office\Lync] "CanSharePptInCollab"=dword:00000001 "CanShareOneNoteInCollab"=dword:00000001 "CanAppShareInCollab"=dword:00000001 "EnableSkypeUI"=hex:00,00,00,00
How to avoid
“EnableSkypeUI” binary value changing automatically to ‘hex:01,00,00,00’ when Lync restarts?
