In Windows 8, 7 and XP, you can set the Windows Firewall to block or unblock certain applications. Here’s how.
Windows 10, 8, & 7
- Open the “Control Panel“.
- Select “System and Security“.
- In the Windows Firewall section, select “Allow a program through Windows Firewall“.
- Unchecking the box to the left of the application name disallows it from accessing network resources, while checking it allows access.
- If the program you wish to block or unblock is not listed, you can click the “Allow another program…” button to add it. Choose the application in the list and select “Add“. If the program is not in this list, use the “Browse…” button to select the program file manually.
Windows XP
- Click Start and open the “Control Panel“.
- Select “Security Center“.
- In the “Manage security settings for” area, select “Windows Firewall“.
- Select the “Exceptions” tab.
- Check an application to allow access to the network, uncheck it to block access. If the program isn’t listed, select the “Add Program…” button to add it to the list.

I have recently had some issues with my firewall blocking applications, but I can still do everything like I used to. The problem is that everytime I open an application I get a notification saying that my firewall has blocked this application over and over again. I tried to allow those applications through the firewall, or to turn off those notifications, but every time I click okay and think it has been solved the setting is automatically set back to the way it was.

My computer is now using Windows 10. I was sent a notice that my internet security (kasperskey) has been blocked.I have been trying to allow it but it doesn’t show up in my list using the method you showed above when i try to add it as a trusted site. It is definitely on my conputer and I have just updated it.The weird thing is it did show Macaffe which i have never installed on the computer. It may have been on there as a potential free trial. I am not computer literate so i need easy explainations to find it if it is somewhere else.

Very useful page, stopped superfetch but I have still got problems with High CPU usage 100% and High memory usage that I didn’t experience before downloading windows 10. I’ve tried other suggestions but nothing seems to work. I may have to go back to windows 7. Cheers.

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.
