writes "Microsoft has confirmed that it is investigating a problem described as the 'black screen of death,' which affects Windows 7 — and reports suggest it affects Vista and XP, too. The firm said it was looking into reports that suggest its latest security update, released on Tuesday 25 November, caused the problem. The error means that users of Windows 7 and earlier operating systems see a totally black screen after logging on to the system." Update: 12/01 22:35 GMT
: Microsoft now says that its November Windows updates are not causing the BlackSOD
: "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."
