After adding the SUA feature to Windows Server 2008 R2 SP1, and updating SUA with the SDK (http://www.microsoft.com/downloads/en/details.aspx?FamilyId=93FF2201-325E-487F-A398-EFDE5758C47F&displaylang=en) and followed the link to "critical updates" (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=2049A1F5-14D0-4DAD-956D-658337AA0130&displaylang=en) on that page, but the link is broken, redirects back to itself (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=2049A1F5-14D0-4DAD-956D-658337AA0130&displaylang=en). Later discovered really important hotfix http://support.microsoft.com/kb/2458000 was needed. What else am I missing? Which begs the question, what are the recommended "critical updates" for SUA or SUA SDK? Especially troubling since the download instructions page's link is broken. Will Microsoft Updates (as discovered, if any) include SUA security updates for the SUA and SUA SDK feature? Thanks for the help. If Microsoft technical support is reading this, please update the "critical updates" link.

Utilities and SDK for Subsystem for UNIX-based Applications in Microsoft Windows 7 and Windows Server 2008 R2 can be found here: http://www.microsoft.com/en-us/download/details.aspx?id=2391 more info on install in Technet there : Installing Utilities and SDK for Subsystem for UNIX-based Applications: http://technet.microsoft.com/en-us/library/cc732759.aspx but no clue on how to find the critical updates regarding this product. When Microsoft will consider its clients as important ?

Besides to above post I suggest you refer this blog for SUA:http://blogs.msdn.com/b/sfu/archive/2010/03/23/sua-sdk-for-windows-7-windows-server-2008-r2.aspxRegards, Ravikumar P
