My friend system is having windows xp on the same. He had updated recently. Everything is working fine except the desktop. It is being rotated to 90 degree and does not goes back to normal. I am a bit annoyed with the same. I am not able to find any solution for this. He called me to fix the issue but the problem is a bit different here. How can I restore the same back to normal. That will be more helpful in fixing the problem.
