So, I read recently that there's an unblocked vulnerability in windows. Microsoft hasn't patched it yet, but you tin cake information technology yourself.

To do so, y'all need to edit the rules in your firewall.
To get there, you go to control panel -> System and Security -> Windows Firewall
– or you can type "firewall" into Cortana, and she'll give you lot a link.

This is what you're looking for:
Firewall full

In one case you get here, click the "Advanced Settings" link on the left side of the screen.
That will bring yous here:
Firewall advanced

From this screen, y'all need to add an outbound rule to cake regsvr32 from accessing the cyberspace.
To do that, click on "OutBound Rules" on the right hand side of the screen.
Now click "New Dominion" on the right hand side of the screen.
Leave the rule blazon on "Program" and choose "Side by side".
New Rule

After you click next, yous'll demand to cull the "This plan path:" push button, and then click browse to observe regsvr on your machine.
choose path

Regsvr32.exe should be located at
%SystemRoot%\System32\regsvr32.exe

in one case yous find it, choose the file and select "Next"
selected path

Brand sure you've chosen "Cake the connection", then click side by side.
block connection

Now brand sure you've chosen "Domain", "Private" and "Public". This volition brand sure that this program is blocked no matter what kind of network you've connected to. Then click "next".
profile

Finally, give it a name that you'll think – in case you need to delete the rule subsequently for some reason. Give a description if you're so inclined, then click finish.
Name it

Now you should come across your new rule in your "OutBound" Rules list.
blocked

Finally, for good measure, you should practise exactly the same thing with "Entering Rules" to block any incoming traffic. It's overkill, and not actually necessary, but there'due south no damage in doing it – and then I did.
