* make Windows load the VirtIO SCSI pass-through driver on boot without reboot or external programs
Prerequisites
* VirtIO SCSI driver (vioscsi) must be installed OR path to the INF-File must be given as argument to the script
* VirtIO SCSI driver (vioscsi) must be installed **OR** path to the INF-File must be given as argument to the script

How to use
either
* install the vioscsi.inf before OR
* tell the script to do it by -InfPath parameter OR
* use virtio-win-guest-tools.exe /S to install it
* install the ``vioscsi.inf`` before **OR**
* tell the script to do it by ``-InfPath`` parameter **OR**
* use ``virtio-win-guest-tools.exe /S`` to install it
depending on the set security policy it might be required to run the script via
PowerShell /ExecutionPolicy Bypass /File <path-to-this-script-file> [-InfPath <path-to-vioscsi.inf>]
``PowerShell /ExecutionPolicy Bypass /File <path-to-this-script-file> [-InfPath <path-to-vioscsi.inf>]``
How does the script work?
* install the vioscsi driver, if requested
* create a software based device via Win32-API
* add some registry settings
* use pnputil to install the driver for this device
* use pnputil to remove the device
* use ``pnputil`` to install the driver for this device
* use ``pnputil`` to remove the device
The driver-to-device assignment marks the driver for being loaded on boot.
Now the Windows is ready for migration to a VirtIO based SCSI disk.
