In Conditions you can select from Publisher, Path or File hash. We don’t want Jack to have access to any of the games. so we will select Path.

Click on Browse Folders and select the Microsoft Games folder.

In the next screen you could add Exceptions like allowing certain files, but because we are blocking the entire games directory we’ll skip to the next screen.

Here you can add a description to the rule so you can keep track of them is there are several rules configured. When everything looks right click on Create.

A message pops up saying default rules haven’t been created yet. It is important to make sure they are created so click Yes to this message.

After creating the rule make sure and go into services and make Application Identification is started and that it’s set to automatically start as well otherwise the rules won’t work. By default this service is not started so you will need to enable it.

Now, when Jack logs into his user account and tries to access the games he will only see the following message. Only an Administrator can go in and change the rule.

Block Install Program Di Windows 7

One of the security features that Microsoft provides to keep your information private is the Windows 7 Firewall. To get the most out of the firewall, you need to tell Windows 7 to allow certain trusted programs to break through.

After all, a firewall is designed to keep your computer safe from outsiders by preventing any one or any program from entering or exiting your computer via the Internet. So, programs that you have that need to access the Internet, such as updating a bank account, are going to be stopped dead in their tracks. To keep things running smoothly, you need to tell the Firewall which programs are safe.

1. Choose Start→Control Panel→System and Security→Allow a Program through Windows Firewall.

   Allowed Programs dialog box

2. Select the check box(es) for the program(s) you want to allow through the firewall.

3. Use the check boxes to indicate the kind of network that has to be running for the program to get through.

   For example, you don’t want the checkbook program accessing your bank account from the local coffee shop — a Public network.

4. Click OK to accept the settings.

   If you want to remove a program from the Allowed list in future, simply return to this dialog box, click the program in the list, and then click Remove.
