We could like to apply the most recent April cumulative update for our MOSS environment. My question is do I have to apply the April cumulative update for WSS 3.0 followed by April cumulative update for MOSS? Or I just need to apply April cumulative update for MOSS only for our MOSS environment? Download WSS 3.0 April 2011 CU http://support.microsoft.com/hotfix/KBHotfix.aspx?kbln=en-us&kbnum=2512783 Download MOSS 2007 April 2011 CU http://support.microsoft.com/hotfix/KBHotfix.aspx?kbln=en-us&kbnum=2512782 Thanks in advance

For the MOSS products, you should apply both WSS and MOSS updates, starting with WSS update first. You need to run the configuration wizard after the last update only. By the way the latest updates are the April 2012 Cumulative updates and not the April 2011 CU: From Stefan Gossners's blog : http://blogs.technet.com/b/stefan_gossner/archive/2012/04/25/april-2012-cu-for-sharepoint-2007-and-2010-has-been-released.aspx The KB articles for April CU can be found at the following locations: KB 2598130 - WSS 3.0KB 2598129 - MOSS 2007 The Full Server Packages for April 2012 CU are available through the following links: Download WSS 3.0 April 2012 CUDownload MOSS 2007 April 2012 CU Dirk Van den Berghe
