For last few days I am getting slow performance in my desktop and OS I have in my pc is XP. I have short knowledge about pc troubleshooting and called one of my friends for help and he is a technical person. He suggests me to stop some software loading at windows startup and uninstall the software which I am not using regularly and he also told me the total process to do it. I have done it as per my friend’s instruction. But I can see a program in the taskbar called windows messenger is still running. I can’t remove or stop it. My friend is not around currently that’s why I need your help.
