I guess somebody is familiary with this problem, I never heard about it. After reinstall Windows XP from Dell CD, it's appear small popup window with caution "You have 30 days for register". As is original I never register software. Yesterday he call me, he can not use Windows. Yes, it's passed 30 days! He describe me, its appear a log screen, but who know for waht is this. How can I fix it for him? Is there any way without reinstalling again?
