A warning to all of our readers in Brazil: If your system is powered by Microsoft's 32-bit version of Windows 7, you should disable automatic Windows Updates. Patch number KB2823324 will cause 32-bit Windows 7 systems in Brazil to enter an infinite reboot loop, something most would like to avoid.
Oddly enough, the problem only presents itself in Brazil: "The problem is isolated to Brazil and we are working on a solution," Microsoft said.
To fix the problem, you'll need to load a recent System Restore points. If you don't use System Restore, you might be able to use Command Prompt in Safe Mode to remove the botched patch. Run the following command:
DISM.exe / image: C: [windows8 install]/ cleanup-image / revertpendingact
Of course, your mileage may vary. If all else fails, you can wait for Microsoft to issue an official fix or reinstall your operating system.
