>pray you never ever get audited for the guest toolkit acceleration.

Worth mentioning that the Extension Pack is distributed separately[1] from VirtualBox itself and requires deliberate installation. Put more simply, it's an opt-in.

I'll also mention that, at least for most personal and even small business use cases, you probably don't need the features provided by the Extension Pack[2]:

* VirtualBox Remote Desktop Protocol (VRDP) support.

* Host webcam passthrough.

* Intel PXE boot ROM.

* Disk image encryption with AES algorithm.

* Cloud integration features.

For what it is worth I get a lot of use out of VirtualBox and I've never seen much point in installing the extension pack.
