The change log for v10.9.2 at http://download.wsusoffline.net/ notes that "This version will be the last one supporting Windows Vista".
Even though extended support for this OS ended on 11-Apr-2017 there are still many Vista SP2 users who are just discovering that their automatic Windows Updates have not been running to completion for several months. I've been posting in the MS Answers forum that Vista SP2 users should use WSUS Offline Update if they are still unable to get Windows Update to run to completion after installing Dalai's suggested speed up patches at http://wu.krelay.de/en/, but it sounds like I'll have to stop recommending this tool once v10.9.3 is released.
Will users who are currently missing security updates for Vista SP2 / IE9 released prior to the end of extended support (e.g., users performing a clean reinstall of Vista SP2) be able to download v10.9.2 tool from the archive and patch their system up to April 2017 once v10.9.3 is released?
If options for Vista SP2 are removed from the Legacy Products tab of the interface, will Vista SP2 users still be able to use the next WSUS Offline Update v10.9.3 release to update other supported Microsoft products like MS Office 2010?
