Microsoft plans to re-issue a security patch for its Windows operating system that caused serious headaches for some users. The MS06-015 security update was released last week, but Microsoft customers soon reported that it was causing applications to crash thanks to a conflict between the patch and NVidia's video drivers and Hewlett-Packard's Share-to-Web photo-sharing software. The new update is presently being tested, and is expected to be released next Tuesday, the same day that Microsoft is scheduled to release its non-security updates for the month.  The update will also provide an automated way of fixing the Windows registry configuration database on affected systems, a work-around that had been previously suggested by Microsoft.
