Cloning a Windows Virtual Machine Fails if the Virtual Machine has a Nonstandard BootExecute Value (2246)
When you clone a Windows virtual machine, the clone operation fails when you power on the virtual machine if the virtual machine has a nonstandard BootExecute value.
When Windows starts, the kernel calls autochk.exe to scan all volumes and check whether or not the volume dirty bit is set. This setting is specified in the BootExecute registry key (located in the registry at HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\Session Manager). The customization process takes advantage of this to run at startup and customize the virtual machine. If this value is not set to run autochk.exe, customization is not be able to run on the virtual machine when the virtual machine is powered on. The result is an uncustomized Windows virtual machine.
To solve this problem, set the value of the BootExecute registry key to the standard Windows value, which runs autochk.exe on startup.
