In my office PC with Win XP Home, when I do the three finger salute to Redmond (Ctrl-Alt-Del) I do not get the screen that I get at home. It is more NT like with buttons of Task Manager, Shut down, Log off etc. And despite pressing task manager, nothing happens lately. Though with XP, I do not see the BSOD, but I had to power off the system to kill the unresponsive application. What could have gone wrong??
