How do I disable the 30 second delay on Remote Desktop connections to Windows 7 when a user is logged in?

I just installed Windows 7 on my laptop. I want to be able to log in using RDC quickly. If I failed to log out or disconnect prior to walking away from my laptop, when I attempt a RDC connection it pops a confirmation dialog up on the laptop and won't connect the RDC connection for 30 seconds unless the confirmation dialog is used.

Is there a way to disable this?

using Local Group Policy Editor (gpedit.msc) there is a setting under :

Administrative Templates \ Windows components \ Remote desktop services \ Remote desktop session host \  Connections

saying "Set rules of remote control of remote desktop services" witch lets you specify the interaction mode and the control level for an RDP session

enable it and choose the "Full control without user permission" option. so the logged user won't be prompt for confirmation (there is more details there)

you can also set the Session time limit for active but idle RDP service under session time limit folder to "Never" and it won't disconnect you you IDLE.

This Microsoft Support article :
Remote Desktop Connection 6.0 prompts you for credentials before you establish a remote desktop connection
suggests turning off this message by text-editing the .rdp file and changing the value of authentication level to zero, like that:

authentication level:i:0
