It may not be the second Tuesday of the month - Microsoft’s normal day to release security bulletins and patches - but the Redmond, Wash.-based developer has posted a critical fix to Windows XP Service Pack 2 (SP2) on its Windows Update site, and pushed it to users relying on Automatic Update.
The problem, which has actually been public since December 2004, also affects Windows Server 2003 and Windows XP Tablet PC Edition 2005. In some cases, installing third-party anti-virus or firewall software - Microsoft didn’t name makers or package titles - can bring down the operating system in a Blue Screen of Death with a cryptic error that reads "Stop 0x05 (INVALID_PROCESS_ATTACH_ATTEMPT)."
