I cannot open Add/Remove program in my system. It was working fine. I want to remove some applications. So I went in control panel and clicked on Add/Remove. It failed to open. There is nothing on the screen. I clicked that a number of time but still the issue occur. I am here trying to do clean my system. While I can open other icons from control panel lime mouse, firewall, etc. Only Add/Remove failed to work. What can be issue here. Is there any separate settings available in windows to turn this feature off. How can I get it back.
