Users will need to review the Font Installation and Deletion, AddFontResource function, AddFontResourceEx function, RemoveFontResource function and RemoveFontResourceEx function to do it.
2. Microsoft is still investigation the second issue but users are allowed to uninstall the updates KB2982791, KB2970228, KB2975719 and KB2975331 by going to the "Control Panel > Programs and Features > View Installed Updates."
