Hi All ! Now a days, I am facing a very strange problem. I don't know the reason. There is no "users" tab showing in the task manager. Because of this, I have re-installed Windows again and the problem was solved. But from last night, task manager is not showing again any "USERS" tab. What can be the reason of this problem? Currently I am using Windows XP SP2, Kaspersky Anti_virus(Trial Version), Zone Alarm Pro(Full Version), Genuine Windows. Kindly guide me , what to do?
