I have recently reinstalled vista and have had problems with constant error messages like "microsoft search protocol,explorer,rundll 32,userini and many applications working installers and even the simple games like freecell and hearts.I have to reinstall every two or so days since the explorer stops responding.I also had a dual boot with xp home which also gave me problems about the same time with a memory dump or something.Both are cracked windows but have never had this problem before.When I reinstall with vista the old windows gets saved as old windows.000 even though it is a total reinstall.I thought it was the new crack I was using but I have tried to install without a crack to no avail.Please help.....
