Just found a much easier way to turn off those frigging annoying rings.
See I just tried doing the "gpedit.msc" program, but it wasn't loading the "snap" right or whatever it's supposed to be doing. And I didn't really think surgically editing every entry in the Registry would be a very wise thing to do, unless you're a really deep Windows registry editing type of person.
So here's what I just did for Windows 7 on my Wacom Intuos3 :
Control Panel -> Administrative Tools -> Services -> Scroll down to Tablet PC Input Service (Not TabletServiceWacom) -> Stop Service.
It's also set to start Automatically, so you may want to turn that off so it doesn't bother you again. Just right click on the
Tablet PC Input Service -> Properties -> Change Startup Type to Disabled.
I'm sure it'll be a whole bunch easier for everyone that way.
Cheers!!
UPDATE: If you want to be an insane person, you can just restart the service and the splash rings will come back.... Good way to annoy the uninformed.
