Hi Sibro,
I have no idea why people have to change to the oobe directory as system32 is a path variable and anything beneath that folder is accessible as well as any other paths a user sets up.
On newer laptops, depending on your setting in bios, you would have to use Shift/Fn/F10. As I use the Function keys F1-F12 more than the Fn functions on a laptop, I change the bios setting so that I would have to press the Fn key for example, to change screen brightness or volume. This really comes down to personal choice.
Regards,
