    Note This security update was rereleased on November 11, 2015, for Windows 7 and Windows Server 2008 R2 to resolve the following issues:

    • Resolves crashing that occurred in all supported versions of Microsoft Outlook when users were reading certain emails.

    • Resolves problems that occurred while users were logging on to the system.

There may be other, similar logon issues that are related to this issue.

    If you cannot log on to your Windows 7-based computer because of this issue, we recommend that you uninstall security update 3097877 and then install all the latest updates from Windows Update. KB 3097877 provides ways to uninstall the update.
