The security warnings when deploying unsigned applications from Visual Studio to a real Windows Mobile device can get very annoying. Thankfully they can be disabled with a hack and here is how.

Using the Remote Registry Editor supplied with Visual Studio and with the Windows Mobile SDK installed change the following key value from 0 to 1 (and vise-versa to reset the change)

HKEY_LOCAL_MACHINE\Security\Policies\Policies\0000101a = 1

That’s it.
