SYMPTOMS

When you are running Hyper-V virtual machines on a Windows Server 2008-based Hyper-V host computer, some Vmwp.exe processes may crash occasionally. This problem may occur when the guest operating system is using an alpha-blended cursor. This problem may also occur when the host computer is running under a stress condition, such as when many virtual machines are running in parallel.
