These downloads are Microsoft’s 2011 monthly security updates for Windows XP. You will need to also download the 2008 and 2009 patches – see the Windows section for a complete listing. The list starts from the most recent and goes backwards down the page. Each item includes the official Microsoft Knowledge Base number – starting with the KB – so you can look them up at Microsoft’s site if needed. Clicking a link will start that patch’s file download.
Really important stuff to read first
The patches are only for the Windows XP operating system. You must install Service Pack 3 plus the 2008 and 2009 updates first. Optional updates, drivers, hotfixes and critical releases for Media Player, Office or other Microsoft products are not included here and must be downloaded separately. For important information about patching your system, see this page.
