The error Windows Live Mail Error ID: 0x8DE00006 pertains to account is temporarily deactivated and what you received is called HIP. It is part of the Human Interactive Proof (HIP) validation process. We have implemented it to verify valid users and to help stop both incoming and outgoing unsolicited messages (spam).

If you're not seeing the picture with characters and numbers when accessing account using Windows Live Mail or any email client, I suggest you access your account on the web based mail and check if the HIP will appear there. Once it appears, fill out the information there and submit. If issue will persist, clear your browser's cache and cookies or use a different browser or computer in VERIFYING your account.
