How to block application in windows 7

One of our reader Samuel complains about his brother “My brother always keeps downloading and uploading using p2p and ends up using all bandwidth and with slow internet connection, is there any way to block utorrent application, but I don’t want to install any software to block them, since he is very good in computer” Basically, Samuel wants to block the application without using any software. I would have suggested to tweak firewall settings to block application from using the internet, but since he mentioned that his brother is good in computers, he might just troubleshoot that problem. So, It’s better just block the application from the system using the registry editor. No matter how good he is in computer, he will never be able to crack this one.

Follow this Simple Steps:

1.) Open Registry Editor, Press Winkey + R and Type regedit and Enter or Go to Start => In search pane type regedit and Enter.

2.) Navigate to following location in registry editor:


explorer path in regedit

Note: If Explorer key does not exit or present, Create a new key named explorer, right-click on policies, select New key and name it as Explorer.


3.) Now in right-pane of Explorer, Create new key named DisallowRun, right-click on the right side pane of explorer, select New => DWORD (32-bit) Value and name as DisallowRun.

Now double click on it and change the value to 1.

4.) Now select explorer key and create a new key under explorer with the same name, right-click on explorer key and select New => Key and name it as DisallowRun (you may see new key as folder icon on the left pane.)

5.) After creating new key under Explorer, create new string under newly created key to block application, Select newly created key under explorer i.e. DisallowRun, right-click on the right side pane, Select New => String Value and name as block uTorrent.
