Microsoft Update KB2823324 has been recalled
Microsoft has recalled one of their recent windows updates yesterday. The update was causing a lot of Windows 7 systems to have a blue screen (
0xc000021a Stop error) or generate event errors with ID 55 and may even cause your system to not be able to boot upon restart.
Microsoft has already removed the update from windows updates list and they are recommending their users to uninstall the update from their systems if they have already installed it.
