VirtualBox VM said The virtual machine has terminated unexpectedly during startup with exit code 1 (0x1)

Today, when trying to play some VM in Virtualbox found an error and following message:

"The virtual machine 'server3' has terminated unexpectedly during startup with exit code 1 (0x1)"

And then:

Fallo al abrir una sesión para la máquina virtual server3.
The virtual machine 'server3' has terminated unexpectedly during startup with exit code 1 (0x1).  More details may be available in 'D:\VirtualMachines\server3\Logs\VBoxStartup.log'.
Código Resultado: E_FAIL (0x80004005)

The only change on my OS system was an Windows update. 

Some registries changed and causes VirtualBox crash. Here is a summary of VboxStartup.log:

Error -5601 in supR3HardenedWinVerifyProcess! (enmWhat=1)

Somes people say it is a AntiVirus related issue, another one relates problem with new Windows Update.

I found a discussion with a "happy ending" by installing an updated version of virtualBox 4.3.18
https://forums.virtualbox.org/viewtopic.php?f=6&t=63556&start=210

So reinstalling the same Virtual Box 4.3.16 didn't work! Then downloaded newest version of Virtual Box ( 4.3.26-98988)

PD: Prior to Uninstall&Install I prefered to backup my server's HDD

And pay attention to data Paths like where your app is installed and where your VM are stored.

FULL uninstall:

New install:

PD: Please, reboot system after uninstall VB, and then atfer VB install, remember it is Winbugs lol

Now my VMs (linux) are running once again! :P
