MC2100 How to enable radio after cold boot?

I have a MC2100 with windows ce 6.0. I tried to create a .reg file as the following and place in the application folder, but it still did not enable the radio after the cold boot. Is there any solution to enable it after a cold boot?

 

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WLAN]

"InitialState"=dword:00000000
