Details at this point are sparse, but it looks like three different patches from this week's Black Tuesday crop are causing Blue Screens with a Stop 0x50 error on some systems. If you're hitting a BSOD, you can help diagnose the problem (and perhaps prod Microsoft to find a solution) by adding your voice to the Microsoft Answers Forum thread on the subject.

Problematic kernel-mode driver updates aren't unusual at all. Now that Microsoft is releasing more of them, problems seem to be cropping up more frequently.

In this case, two MS14-045/KB 2984615 kernel-mode driver patches, KB2976897 and KB2982791, have been implicated in triggering Blue Screen Stop 0x50 messages. Oddly, the Windows 8.1 "Update 2" fix that adds the ruble character as an official currency marker in Win 8.x and Win7, KB 2970228, seems to be causing the problem, too.

At this point there's no word on possible causes, although several people have identified their operating systems as 64-bit Windows 7.

If you hit a blue screen after installing this week's Black Tuesday trove, drop by the Microsoft Answers Forum and sound off.
