Disabling Message Center in RealPlayer via a simple registry edit

Random tidbit of potentially useful information...

From a comment by Wulf on the Google Operating System blog:

While playing around in my Registry, I found an interesting entry from RealPlayer.

If you change

HKEY_CURRENT_USER\Software\RealNetworks\Msg\
Preferences\Frequency > (default)

from 1 to 0, the 'Message Center' (read: ads) won't come up anymore...

I haven't tried this, as I so rarely use RealPlayer that I don't even remember the annoyance that this tip claims to prevent. But, I did go ahead and make this registry value change, in the hopes that someday, something might less annoying. :)

I actually took this opportunity to try out REG.EXE, the "Console Registry Tool for Windows" (it came with Windows XP Pro), which I've never gotten around to messing with... So this is how I changed this particular registry key:
reg add
HKCU\Software\RealNetworks\Msg\Preferences\Frequency
/ve /d 0
