Microsoft says MS14-045 some KB updates should be uninstalled due to crashes.
Two of these (2970228 and 2975719) are among the updates withdrawn by Microsoft along with MS14-045.
A reboot must be done after the Updates is uninstalled in the ‘Program and features’, installed updates section.
So in effect the fix to the Kernel bug is now broken, thus requiring you to uninstall or wait for a better patch. I have uninstalled.
