Thread: How to unblock the program?

I was doing some work in Vista. Suddenly, a pop-up window came and clicked on Keep Blocking button. Don’t know what it was. Is there anyway to unblock that program? How?

Click on Start and type msconfig and hit Enter. Then, click on the Startup tab and check the program which is disabled. If you want to that program at the Startup, then just select the checkbox and click on Apply and click on OK. Then reboot your system.
