Hi everybody a while ago windows won't shutdown anymore !! I did some research and found the problem in the registry key HKLM\SYSTEM\CurrentControlSet\Control\Session Manager The key that prevents windows to shutdown is BootExecute value autocheck autochk * If I delete the key then windows shutdown normaly !! I did check all my drives with chkdsk and no problems where found there Does anybody know how I can fix this without deleting the autocheck key ??
