You're not a PITA.
What's a PITA is that Windows has Recovery options in the Control panel and it also has some in the new Metro tile section, so it's no wonder you didn't know where to find it.
I'm doing this by memory, so might not have the exact words, but the path should be good enough for you to get there.
Pull out the Charms bar and hit the Settings icon, then Hit PC Settings at the bottom.
On the subsequent page that opens up, hit the General tab, then scroll down to the very bottom of the page where there will be an option that offers to restart into recovery (can't remember the term they use, but it's the last option on that page.
Once you get into the recovery area, you'll be looking for "Advanced Start up" (or something similar), so on that first page, you'll hit 'Troubleshoot", then on the next one, "Advanced Settings" (or something similar) and on the third and last page, you'll see the advanced start up option and you click on it and a confirmation page will open up, then you hit OK and after a small reboot, you'll come to a page that allows you to choose the options by number, so type in the number to the option that corresponds to disabling the driver signing enforcement and then it'll boot up and you'll be able to install that driver.
All is well in Paradise.
