We had earlier recounted how Microsoft was bungling with its patches notonceortwicebutthreetimes in the recent past.
This is being done since 2003 and is known as Patch Tuesday or Black Tuesday.
This corruption would be rectified if the patch was uninstalled.
Also it was found that the patch does not affect the Windows 7 and 8.1 versions.
The problem lies that, Microsoft published this patch without documentation and proper instructions regarding the patch.
Users who have previously installedKB 3013455need to now install KB 3037639 and the font issue was rectified.
Also users can directly installKB 3037639 instead of KB 3013455to tackle the vulnerability in Windows Kernel-Mode Driver.
