Disabling Win 7 x64 Driver Signing

[NickM]

I have an unsigned driver that I want to run, on x32 is was no problem but having moved to x64 it wont run.

1) How safe is disabling driver signing?
2) Is there a better/more permanent way than F8 every time I boot the computer?

Thanks

Its the driver for Virtual Audio Cable which seems ok. If I disabled it though then I guess anything could install drivers but I suppose that would be no different to x32.
