It does not exist
Microsoft claims that reports that its recently security
updates create a “black screen of death” have been greatly exaggerated.
British software security firm Prevx claimed last week
that changes to Microsoft's operating system's registry were the most likely
cause of the error. Initially both believed it was a recent patch issued by
Microsoft. Now it seems that this was not the cause.
The problem was widely reported after a small number of
users were presented with a completely black screen after logging on. A spokesman for Microsoft said that reports claimed that
its November security updates made changes to permissions in the registry that
are resulting in system issues for some customers.
However the updates did not do that and could not have
caused the behaviour described in the reports. So far Microsoft is not seeing this as a big issue and
Prevx has apologised to Microsoft for the “inconvenience” caused by its
original blog posting.
Apparently the black screen could be caused by malware or
other programs and urged Windows 7 users to continue updating the operating
system and security software.
