  • 3097877 MS15-115: Description of the security update for Windows: November 10, 2015


    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. For example, after a user restarted the computer and then pressed Ctrl+Alt+Delete at the logon screen, the screen flashed and then went black. The user was then unable to continue. 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.
