An enterprise hotfix rollup is available for Windows 7 SP1 and Windows Server 2008 R2 SP1
This is a collection of the various updates we kept (we being PFEs who do WDRAP in particular) and Yong Rhee published for us, like http://blogs.technet.com/b/yongrhee/archive/2012/02/19/list-of-performance-hotfixes-post-sp1-for-windows-7-sp1.aspx.
This is now a Rollup for Enterprises. It is not in Windows Update, but is in the Catalog here:
Most customers should see a minute or more reduced from boot, and a more peppy system, as a result.
This was a great collaborative effort amongst CTS, WINSE, PFE and MCS. A huge thanks to everyone involved.
How do we deploy updates 2732673 and 2728738 with ConfigMgr. They aren't in the WSUS catalog or the Microsoft Update catalog it appears
