Hello,

is it possible to install virtualbox WITHOUT any modification (drivers, etc..) on the host system (windows 8.1) ?

thanks by advance

No. What use would it be to install VirtualBox when you cannot start any VMs?

If you build from sources yourself, you can build VirtualBox and not install any drivers but for any VM to run and use utilities like VBoxManage to only create/modify VMs but to actually run VMs drivers are necessary.

sad because i do not trust these drivers i saw for exemple that before they even destroy the internet access on the windows 8.1 host look to be repair now ...

truecrypt for exemple run the driver only when it's launch (when you install it in portable mode)

i m just affraid that these drivers interfere with the host system ...

You can avoid installing network and USB drivers. The Windows installer gives you the option to skip these because well, you don't need the network drivers unless you are using Bridged Networking or Host-Only networking for your VMs. Similarly, you don't need the USB drivers unless you're trying to pass thru host USB devices to the guest in the VM.

However the support driver (vboxdrv) is not optional if you want to start any VMs at all.
