Right on schedule, Microsoft rolled-out an onslaught of patches for
its "Patch Tuesday" last week, and despite the fact that it wasn't the
true "Update 2" for Windows 8.1 many of us were hoping for, updates are
generally worth snatching up. Since the patch rollout, it's been
discovered that four individual updates are causing random BSoD issues
for its users, with KB2982791, a kernel-mode related driver, being the
biggest culprit. Because of the bug's severity, Microsoft is
recommending that anyone who updated go and uninstall a couple of the
specific updates, or rollback using Windows Restore. You can uninstall
these updates in much the same way you uninstall any app; the difference
is that once you're in the "Programs and Features" section, you'll need
to click on "View installed updates" on the left. While it's mostly
recommended that you uninstall 2982791, you may wish to uninstall the
others as well, just in case.
Security Update for Windows 8.1 for x64-based Systems (KB2982791)
will cause this issue on it's own.
and
Update for Windows 8.1 for x64-based Systems (KB2975719)
will also cause this even if KB2982791 is not installed.
