Apparently something in my most recent automatic update from Microsoft for Windows XP went wrong. On attempting to install the updates during shut down, it got hung up on the 1st of 3 or 4 updates and stayed there in what appeared to be an endless loop. Since then, the system continues to try to install this garbled download during shut down and hangs up all over again. I'd like to remove the aberrant file but I don't know where to look for it. 'Anybody got any ideas?
