Main Page	Windows Root Certificate Program · This is the main page for the Windows Root Certificate Program.

WSUS Availability	NEW - In December 2012 we provide full x86 and x64 availability of the KB931125 root update package via Windows Software Update Services (WSUS) for information technology administrators to deploy the latest Microsoft product updates to computers that are running the Windows operating system. Well, almost - this month we forgot to add a download for x64 Windows Server 2008. Not to worry - WSUS administrators, the x64 bit version for Windows Server Essentials 2012 is bit-identical, and will easily install on Windows Server 2008. In fact, all x86 and x64 bit root update packages are bit-identical and can be interchanged for WSUS deployment. We will make a specific version available for X64 Windows Server 2008 in the next root update coming in 2013.

A Note on amending these wiki pages

Please don’t amend these pages. I realize that the Spirit of the Wiki ™ is for everyone and everyone to modify wiki content at will. I ask that you do not do so – this wiki is a simple and direct method for me to post information about the Windows Root Certificate Program, and most of the content constitutes static Program requirements which does not allow for public editing. Your edits may wipe out the existing content, and can render it temporarily inaccessible to other readers.

So please, do not amend the Program wiki pages just to ask me a question or to seek clarification of something posted - email me at casubmit@microsoft.com.

We're all in this thing together.

Best Regards,

Tom Albertson, Program Manager
