Hi caiustitus, I recommend you submit a support incident to our Windows Update group via the following link: https://support.microsoft.com/oas/default.aspx?&c1=509&gprid=6527& The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the newsgroups regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding. Also, for your information, I'd like to include the following KB article regarding the issue: You cannot download updates when you access the Windows Update Web site from a Windows XP-based computer that is behind a firewall or a proxy server http://support.microsoft.com/kb/896226 Note: Though this KB article is for Windows XP, you can still try the steps on Windows Vista based computer. Hope this helps!Sean Zhu - MSFT
