Oracle VirtualBox has finally released version 5.2.22 which works properly with Windows 1809 or otherwise with the October 2018 version.
With the October 1809 update of Windows 10 the free program Oracle's VirtualBox could not start them virtual machines, whether these were old, or whether you were making new ones.
IGuRu had it points out in a relevant article its from the first moment. But it took a whole month for Oracle to release a working version. So version 5.2.22 of VirtualBox is no longer a problem, so Windows 1809 users will need to upgrade.
Logically, if you run your VB, it will notify you of the existence of 5.2.22, so proceed to download and install it. If he does not notify you then download it from here.
The strange thing is that in the meantime the Oracle people released a version, 5.2, which previously solved problems of the application but it had no effect on the latest Windows 1809. It seems that this version was almost ready to be introduced and at the same time seeing that Windows 1809 had a failed appearance, with a bunch of problems that caused it to be recalled, so the Oracle technicians they proceeded to release it, waiting for Windows to release a pre-release version.
However, those who had downloaded 1809 from the beginning waited a month to see the virtual machines work again.
