Microsoft notes that "To avoid this problem, install update 937287 separately from all other updates." The 937287 update is available here (x86) (x64).

Although Microsoft Corp. has yet to fix an update that sent some Windows Vista machines into endless reboots, today it spelled out several workarounds users can apply to regain control of those PCs.

Last week's update -- actually a pair of prerequisite files that modify Vista's install components to prep the operating system for Service Pack 1 (SP1) -- caused some systems to reboot over and over, while others simply balked at booting. On Tuesday, Microsoft reacted to a flood of reports on its support forums by pulling the files from Windows Update until it could determine what went awry.

Although some users managed to stop the rebooting on their own or with help from others posting messages to a Microsoft support newsgroup, Microsoft was officially mum on a fix or workaround until today.

The KB949358 support document confirmed what users had been reporting for more than a week.

"When you try to install an update from Windows Update on a computer that is running Windows Vista, you may receive the following message: 'configuring updates stage 3 of 3. 0% complete,'" it read. "After you receive this message, the computer reverts to the screen that displays the same message. Additionally, the update is not installed successfully, and the computer restarts."

The document also gave users three ways to stop the rebooting and take back control of their PCs. It suggested that users try them in this order:

Start Windows Vista by using the Windows installation media, and then select the "Repair your computer" option. Start the computer in Safe Mode, and then use the Repair or System Restore feature. Rename the "Pending.xml" file, and then edit the registry.
