Make sure you have KB958644 installed.

Early Friday, the Finnish firm revised its estimate of the number of computers that had fallen victim to the worm, and explained how it came to the figure. “The number of Downadup infections [is] skyrocketing,” Toni Koivunen, an F-Secure researcher, said in an entry to the company’s Security Lab blog . “From an estimated 2.4 million infected machines to over 8.9 million during the last four days. That’s just amazing.”

On Tuesday, Koivunen put the number of infected systems at 2.4 million, then updated the estimate Wednesday to 3.5 million, an increase of 1.1 million in just 24 hours .

Sacrifice your Facebook friends for a Whopper?

I just saw this article on Digg, I thought it was pretty funny.

Fast-food chain Burger King has created “Whopper Sacrifice,” a Facebook app that will give you a coupon for a free hamburger if you delete 10 people from your friends list.

Burger King has put out some interesting campaigns as of late (“Whopper Virgin,” “Subservient Chicken”), but this one piques our interest because of how gleefully it pokes fun at our social-networking obsessions. “Now is the time to put your fair-weather Web friendships to the test,” the Whopper Sacrifice site explains. “Install Whopper Sacrifice on your Facebook profile, and we’ll reward you with a free flame-broiled Whopper when you sacrifice ten of your friends.”

I’m tempted to do it, but if I delete 10 Facebook friends I won’t have any left…

How to change from ACPI Multiprocessor HAL back to ACPI Uniprocessor HAL in Windows 2003

Posted on January 9th, 2009 webmaster 4 comments          Print

“Warning: Changing the number of virtual processors after the guest OS is installed may make your virtual machine unstable.”

You’ve probably seen this message before while working with VMware, especially if you’ve done physical to virtual migrations.

As a best practice, it is recommended to always start with only 1 vCPU when creating virtual machines and only increase the number of vCPUs if you think it’s necessary and if the virtual machine is actually running applications that can utilize multiple processors to avoid wasting resources.

Increasing the number of processors from 1 to 2 or more is actually not a problem with Windows Server 2003 because it will automatically change the HAL to ACPI Multiprocessor PC.  But setting the number of virtual processors back to 1 won’t automatically change the Windows 2003 HAL back to ACPI Uniprocessor PC.

According to Microsoft, “If you run a multiprocessor HAL with only a single processor installed, the computer typically works as expected, and there is little or no affect on performance.”  But if you’re like me and just want to be absolutely sure that there won’t be issues, switching back to the uniprocessor HAL in Windows Server 2003 is pretty easy:

1. Make sure you have at least Windows Server 2003 Service Pack 2 installed.
2. Shut down the virtual machine.
3. Change number of virtual processors to 1.
4. Power on the virtual machine.
5. In Windows, go to Device Manager -> Computer.
6. Right-click “ACPI Multiprocessor PC” and choose “Update Driver…“.
7. Select “No, not this time” option -> “Install from a list or specific location” -> “Don’t search.  I will choose the driver to install.” -> select “ACPI Uniprocessor PC.”
8. Reboot the virtual machine.

That’s it! You’re all set!
