    I just installed Windows 10 Pro, Technical Preview, and whenever, I use to click on Advance settings for Windows Firewall, I received an error saying “Microsoft Management Console” has stopped working.

    Since I wanted to set a rule for inbound and outbound port, I came to this link and VOILA :-) That red rectangle, saying click on Allow an app through a Firewall, did the trick for me.

    Many CHEERS and KEEP SMILING :-)

    Hi,

    Found this really helpful.
    Been so long since I have gone into Firewall
    settings.

    For those really new to doing this
    and not sure of some meanings of regular
    english words:

    the word ‘Check’ (see instructions
    for XP above). Point number ‘5. Check an application…’
    Check means a tick (left-click inside the box)
    Uncheck means a blank box.

    Thank you to the creator of this page.
