Microsoft pulls four Windows 8.1 patches over instability, crashes

updated 12:42 pm EDT, Tue August 19, 2014

Microsoft-provided fix involves registry modification, manual deletion

Plagued by crashes, Microsoft has retracted its Windows patches from August 12. Users that have installed patches 2982791, 2970228, 2975719 and 2975331 are at risk of system instability, or a "0x50 Stop" error on startup, which prevents the system from booting. A fix requires either a clean OS install, or registry modification to purge the afflicted updates.

The issues developed immediately after patch launch, and was supposed to be used for "correcting the way that Windows handles thread-owned objects, by correcting the way in which specially crafted font files are handled in memory by Windows, and by correcting the way in which memory is allocated."

Microsoft still doesn't have a handle on the situation, other than some font management and rendering issues. To rectify the problem, users should boot into Safe Mode, delete "fntcache.dat," and edit the registry using Microsoft-provided instructions to manually delete the patches. Alternatively, a clean OS install works as well, assuming the patch isn't reinstalled.
