My friend made the huge mistake of downloading PartyPoker onto a laptop from work - even after he uninstalled it, the menu item still showed up. He was worried about getting caught by the IT people, so he asked me how to get rid of it.
It seems like every worthless application out there feels the need to infest the Tools menu in Internet Explorer with unwanted entries, and uninstalling the application almost never removes the menu item.
To get rid of this entry, and potentially any others in the list, we’ll have to venture into the registry. Open up the registry editor by typing regedit into the run box.
Browse down to the following key:
Under this key, you will see a lot of subkeys with really long names. Click on each one of them, and if you look in the right hand pane, you will see the menu text from the offending menu item. For instance, you can see in this screenshot that I’ve selected the key that contains the PartyPoker menu item.
Just right-click and Delete the keys that you don’t want to show up. Restart Internet Explorer, and the menu item should be gone.
This tip should work for either IE6 or IE7.
