From A-Patch: "That’s right! After a few requests (and some help by osmosis on joining the then closed beta) I finally got around to making an ad-remover for Windows Live Mail Desktop. At the moment there is only one option (removing the ad) and it should work on future versions of WLMail Desktop without having to update A-Patch. Although if it doesn’t work on an upcoming version, then God-Willing, I will be updating it for everyone. "So what exactly does it do? Simple, it removes the tall vertical advertisement on the right-hand side of WLMail Desktop (and the space it takes up!). You can find A-Patch for Windows Live Mail Desktop along with A-Patch for Windows Live/MSN Messenger in the downloads section.
