Several blogs said that Windows users who thought they had automatic updates set had their machines pached and rebooted.

Microsoft said that Aoutomatic Update Mechanism is no change. And the company also said that recent update didn't change Automatic Update settings.

The company is looking into whether customers might have actually had their settings changed by Microsoft Office or Windows OneCare, two programs that do have mechanisms that will change a computer's automatic update preference settings.

Meanwhile, in a separate posting, Clinton acknowledged that some people are having trouble manually installing updates after moving to the latest version of Windows Update.

Free Windows Software

Ultimate List of Free Windows Software from Microsoft

Microsoft has over 150 FREE Windows & Office Programs available for download -- finding them all is extremely difficult . . . until now.

F-Secure BlackLight Update
This is an AntiRootkit Tool.

We've just published a new beta version of our free BlackLight rootkit scanner, which now also supports Windows Vista (32-bit only) and Windows 2003 Server x64 Editions.

The same BlackLight executable will work on all supported platforms.
You may find it interesting that we're adding support for 64-bit operating systems, even though there are currently no rootkits for them! The reason is that while 32-bit rootkits do not work on 64-bit platforms it is not impossible to create a 64-bit compatible rootkit. It just requires extra effort.
For example, a user-mode rootkit would have to hook 64-bit processes with 64-bit code but also make sure everything is hidden from 32-bit applications running under WOW64 emulation. As the number of computers running 64-bit Windows has remained low, the rootkit authors have not had a reason to spend the extra effort to target those systems. When they do, we hope to be ready.
