Beat Downadup/Conficker like a Pro

Since there are many websites talked for days about Conficker/Downadup. Today, I have something different especially for system admins.
I've been busy for the last three days, building defense lines around critical servers for one of my customers. The source of infection was due to one lazy user, who has no antivirus installed on his laptop. And it didn't take a long time to start spreading and attacking other systems in the network. We have responded fast, otherwise, we would spend the rest of the day, counting how many critical systems are down.

Windows XP SP3 Setup Error: Access is Denied, Installation did not Complete.

As we all know Microsoft has released the final version of Windows XP SP3 to public and its available via Automatic Updates, Windows Updates and Downloads Center.

Windows XP SP3 RTM Available on Windows Update, Automatic Update and Download Center

You can download the SP3 from the Microsoft website.

A few people are facing a problem while installing SP3. Whenever they try to install it, Windows shows following error message:

Service Pack 3 setup error. Access is denied.

Programming with MSMQ: and it's installation issues.

MSMQ has already been there for while. Actually it has been here at least 5-6 years (that is only the time I am familiar with it).
The Idea of it is pretty simple:

1. You have an application with some logic.
2. Part of this logic is to perform asynchronous calls to some other application logic.
3. You do not wish that it will affect your performance.
4. The order of handling those calls has to preserve - the FIFO method.

Disassemble a Gateway 610 Media PC (Elonex Exentia)

I was looking to 'fix' my Gateway 610 it stopped booting, or mearly started to freeze up 5 minutes or 40 minutes after boot, mid-video playback. I assumed a background task, or maybe a virus. Soon the reboots messed the boot drive, and sometimes it wouldn't recognise the drive.
