Windows: The last updates from Microsoft have caused a headache for some users. A bug in the update causes certain programs to fail to render properly blacking out the whole screen. A third-party security company has released a fix.
The problem—according to Prevx, the security firm that released a patch to fix the issue—involves the Microsoft patches altering the way registry keys are accessed:
[...]the cause of this recent crop of Black Screen appears to be a change in the Windows Operating Systems lock down of registry keys. This change has the effect of invalidating several key registry entries if they are updated without consideration of the new ACL rules being applied. For reference the rule change does not appear to have been publicised adequately, if at all, with the recent Windows updates.
If your black screen woes started as a result of your last Windows update the Prevx patch should have a high probability of fixing the issue. If you don't have automatic update enabled you'll want to skip doing any updates until the next patch release comes out and corrects the black-screen-of-death issue.
