How do I force the SIP keyboard on Windows Mobile to read new settings from the registry?

Question

I'm disabling auto-complete and auto-suggestion on Windows Mobile 6.1 by setting the following registry keys:

HKCU\ControlPanel\Sip\SuggWords => 0
HKCU\ControlPanel\Sip\SuggAutoCorr => 0

However it doesn't seem to change anything until I restart the device. The control panel applet that exposes these settings somehow tells the SIP keyboard to reload, but how?

One of the most common mechanisms the OS uses for these types of things is broadcasting a WM_SETTINGSCHANGE message. I don't know that this is what the CPL does in this instance, but it's certainly worth a try.
