A computer that is running Windows Vista or Windows Server 2008 stops responding at a black screen early in the startup process

When you start a computer that is running Windows Vista or Windows Server 2008, it stops responding at a black screen early in the startup process.
The issue occurs because of a deadlock between a thread in Windows NT File System driver (Ntfs.sys) and a thread in the Autochk.exe program.
Important This issue may occur sometimes or every time that you start the computer. If you can load Windows successfully, apply this hotfix. If the issue occurs every time when you start the computer, contact Microsoft Customer Service and Support.
