Microsoft Corp said on Tuesday it had found no evidence that its recent security updates were causing problems with its new Windows 7 operating system, which some users said left them with a black screen of death.

Microsoft has investigated reports that its November security updates made changes to permissions in the registry that that are resulting in system issues for some customers, Microsoft security response communications lead Christopher Budd said in a statement.

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.

Budd added that Microsoft's support teams were not seeing this as a big issue as the claims also do not match any known issues that have been documented in the security bulletins or (knowledge base) articles.

The problem was first identified by British software security firm Prevx last week and who then went on to make a blog posting on how to restore the computer from the frozen black screen.

Microsoft said in the statement that it had not been contacted by Prevx before that company went public with its claims. Microsoft said it has reached out to them to let them know the results of its investigation.
