Finally,I guess this problem is caused windows update, and it is a bug in windows update or virtualbox, so i install an older edition VB, VirtualBox-4.3.0-89960-Win , after that ,when start VB ,another problem comes up,'virtualbox cannot access the kernel driver' ,so I do like this:
1\Close VirtualBox Open regedit.exe from the Start Menu Navigate to HKEY_LOCAL_MACHINE\system\currentcontrolset\services\vboxdrv
Double click the name ImagePath
Change the value to \C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv\VBoxDrv.sys ,
then Go to C:\Program Files\Oracle\VirtualBox\drivers\USB\filter Select VBoxUSBMon.inf and click the right mouse button. Then pick Install.
Go to C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv Select VBoxDrv.inf and click the right mouse button. Then pick install.
