Unfortunately the following registry tweak seems to affect Secure Desktop globally...
QUOTE
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList]
"Administrator"=dword:00000000
"Administrator"=dword:00000000
Is there another way (GPO?) to achieve the effect without the problem shown below?
[EDIT] This even happens with "All elevation requests will go to the interactive users desktop" Enabled
before tweak

after tweak
