Microsoft Dynamics CRM publishes Update Rollups to the Microsoft Update site when each update is released. Currently all the Update Rollups are available on the Microsoft Update site. Going forward we will maintain the three most recent Updates Rollups. On 4/19/2012, we will expire and remove our older Update Rollups from Microsoft Update. The removal of the Update Rollups does not affect the Microsoft download center
http://www.microsoft.com/download. You will still be able to download all the previous Update Rollups from the Microsoft download site.
Below is the current schedule for the content to expire. On the expiration date, the binaries will disappear from Microsoft Update at 10 am (Pacific). Update Rollup 6 will be an exception and not expired because Update Rollup 6 is required for future Update Rollups to be installed.
