Having .Net servicing issues?

  I wanted to make everyone aware of a new blog entry I wrote for my teams blog regarding .Net servicing issues.  It’s located here: http://blogs.technet.com/b/askcore/archive/2010/07/12/are-you-opening-up-a-net-case-with-microsoft.aspx Because the .Net Framework is both an inbox and out of box installation, it can routinely hit my team as well as some of the developer teams.  This should…

I wanted to talk a little more about the way things work inside of the component store and how things are actually built inside of the servicing mechanisms in Windows.  So, today we’ll look at how the various packages and manifests are manipulated for a specific feature, in this case Chess Titans, and how that…

Servicing Windows: Part One

I wanted to do a multi-part blog from a high level on how servicing in Windows works.  The majority of this will apply to Vista, Win7, 2008 and 2008R2, however there are some things that happen in Win7/R2 that do not happen in Vista/2008.  When appropriate, I’ll try to call those out. So first, a…

Where is VSP1CLN on Windows 2008?

Using CheckSUR and update packages to fix corruption

My last post was on CheckSUR and I wanted to follow it up with how you can use the CheckSUR utility to fix corruption errors that CheckSUR might detect, but that cant be fixed with the utility. Typically, the way that CheckSUR works is that it takes the information included with its payload, loads it…

Why does CheckSUR take a long time to run?

I’ve been asked a lot recently about the CheckSUR utility that our engineers send to customers to assist with servicing corruption issues.  I typically ask that all of our engineers run this tool regardless of the “ease” of the potential fix and the utility gives us a lot of information about the state of the serviving…

What is blobs.bin and why does it grow?

Recently I have been asked a couple of questions about the \Windows\winsxs\ManifestCache\blobs.bin file and what it does. Specifically, the question I have been asked it why the file takes up the amount of space that it does, or in some cases, grows out of control.  In looking around on the web, I’ve seen various explanations for…
