You can use the following command that will create and configure the LocallAccountTokenFilterPolicy DWORD to disable the UAC remote restrictions.
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" /f /v LocalAccountTokenFilterPolicy /t Reg_DWORD /d 1
This command can be executed inside the Run Command box, or an elevated Command Prompt or PowerShell instance. After running the command, restart the computer for the changes to take effect. (creo que no hace falta reiniciar a veces. Probar.)
