Well this particular helped me many times to fix the problems of mine hence I have returned again with another problem. Hence I am hoping that this time also all the users on this forum will help me out to fix the problem of mine. I am getting following error message on the screen when I am trying to turn off the computer. The error message can be stated as follow. ‘logon.scr - application error The application failed to initiate properly (0xc0000135). Click to terminate application.’ Can anyone tell me why this problem is happening on the computer of mine. Any suggestion would be highly appreciated.
