How to fix the Blue Screen BSOD (0x50) after applying update KB2982791 to Windows 7 64 bit from the Patch Tuesday Windows Updates from Aug 2014
Something in that file is triggering the BSOD.
Delete that file and the system will reboot without a bsod.
FNTCACHE.DAT will be recreated upon reboot, so there is no risk to deleting it.
Solution #2 - Uninstall Update KB2982791
I have included the package name for Win7 x64.
wusa /uninstall /kb:2982791 doesn’t work in the recovery console, you have to use DISM.
