"You've opened a new tab" annoyance on IE7

It's annoying to see the following page everytime I open a new tab window on IE7. Even after I check the "Don't show this page again" checkbox, it is still opening a new tab with this annoying "You've opened a new tab" tab.

How do I turn this off to just show my blank home page?

Open the registry by going to Start -> Run -> Type regedit
Look for the following registry
HKEY_CURRENT_USER \Software\Microsoft\Internet Explorer\TabbedBrowsing

Right click on the right window and open a new DWORD value.

Give the name "ShowTabsWelcome", and right click to modify the value. Make sure is shows 0.

Now open a new tab in IE7, the annoying "You've opened a new tab" page is gone!
