Microsoft denies that its patch causes BSOD

After investigation, Microsoft says its patches are not faulty

Microsoft has finished its investigation into claims that a recently released patch is causing a black screen of death and says it's just not true. The company's Security Response Center blog says, "We’ve investigated these reports and found that our November Security Updates are not making changes to the system that these reports say are responsible for these issues."

A Microsoft spokesperson told Microsoft Subnet, "The company has found those reports to be inaccurate and our comprehensive investigation has shown that none of the recently released updates are related to the behavior described in the reports. While we were not contacted by the organization who originally made these reports, we have proactively contacted them with our findings."

According to Microsoft, none of the patches in the November Patch Tuesday, nor the changes in the Windows Malicious Software Removal Tool, nor any of the non-security related updates pushed out in November make "any changes to the permissions in the registry."

Microsoft Security goes it one better -- saying that the company has not received a lot of customer support questions about BSODs and then hints that the BSOD might be caused by a virus, such as Daonol. That's a subtle slap at the wrist at the company that gained a bit of notoriety by going public with its conclusions of a faulty patch, instead of quietly coming to Microsoft. The company that reported the bad patch was Prevx, makers of anti-malware software. Prevx even went so far as to offer for free its own fix for the allegedly faulty patch. Microsoft's hint that a six-month-old Trojan may really be to blame comes awfully close to saying that Prevx's software can't be trusted to detect such things for its users.
