    Some applications may crash after installing Windows Update KB3132372

    Since installing Update 3133431 the Bitdefender firewall is blocking all internet access unless I disable "Block Internet Connection Sharing".

    Is this expected correct functionality? I'm not using Internet Connection Sharing, unless it's being used under the hood for all apps to have internet access. Regardless, this setting to block internet connection sharing has been on since day one.

    Is this a Windows 10 bug (seems to be) or a Bitdefender bug (assume not)?

    The machine with the problem is a desktop using a hardwired network connection - no wi-fi. I have two other laptops that have not shown this issue, yet. I will report back if they successfully installed these two Win10 Flash Updates and do not have the
    same issue with that Bitdefender Firewall setting.

    UPDATE:

    One of the laptops that's on wi-fi has indeed picked up both Win updates and is running Bitdefender with "Block ICS" enabled. No internet issues with that machine.

    This may be a wired networking issue only.
