Probably not affecting anyone here but it may help a friend or family member. So I thought I would post it up.
May 15, 2008 (Computerworld) A former Microsoft Corp. security manager has published a tool designed to detect and fix PCs that may be susceptible to "endless reboots" if updated to Windows XP Service Pack 3 (SP3).
Jesper Johansson, once a program manager for security policy at Microsoft and currently an MVP (Microsoft Most Valuable Professional) who works at Amazon.com, posted a link to the tool on his blog yesterday, beating his former employer and Hewlett-Packard Co. to the draw. Neither company has yet come up with a fix or patch for the weeklong snafu.
