• Windows Vista is one of the worst Windows versions that ever existed. Regardless of the service packs it has received. A overly annoying UAC and other things...
  
• Windows Vista has no support for Microsoft (11.04.2017 < end of Vista support).
  
• Due to the point above you will NOT get any updates (not even security updates) for Windows Vista.
  

You shouldn't be using Windows Vista if you even care a bit about the security of your system! Unfortunately Windows 7 is no solution to this issue because its support ends in 2020.

You could use Windows 8.1 which has extended support til 2023! It's faster than Windows Vista and 7 due to the improvements that Microsoft introduced with Windows 8. Faster booting, overall faster performance and other things.

Or simply get the latest version of Windows 10 and use stuff like ShutUp10 to disable all the telemetry. If you don't like the feature updates you can get the Enterprise LTSC version that only gets security updates and no major feature updates that require bascially a OS reinstallation when they're being installed.


Once you have decided which newer Windows version you want to use I would start thinking about protection. As far as I know, if VBox is so important for you, you can still install it normally on Windows 8.1 and 10. If you run the OS inside a VM there is this thing called "Guest Drivers and Addons".
