When I do Alt+F4 on pure clean cmd console in fullscreen mode it does exit out of the console process (a disk is working for split a second) but it fails to close the console window after that, so I have frozen computer. The operating system seems to run normally under that, but I cannot do anything on the computer then since all I got on screen is a dead console, it doesn't react to any key combinations, only thing that I can do then is just hard restart by holding power button several seconds.
Have you any idea what's going on ? This is on my laptop and I never used full screen console before here so I don't know what I might done to have this. I have run some 'optimization' reg's and cmd's here to disable some services, but now I don't know which setting might it be.
edit: originally I wrote that the system was sp2, it is actually sp3
edit2: It behaves strangely on entering full screen too. For some seconds I'm presented with black screen, it looks like frozen, but after a while content do show. But on end if I forget to go out of full screen before exit I got situation of no return.
