Windows 8 password, ctrl-backspace

An acquaintance of mine just bought a new laptop today. On Windows 7, he has been used to using the character generated by Ctrl-Backspace(ASCII 127) in his password. In fact, his password was simply 3 times this character, because he figured it would be hard to guess.

So he boots up his new laptop that has Windows 8 on it, and uses the same password when creating a user account. This works fine here. However, when he tries to log on, the Ctrl-Backspace combination does not work. Neither does using alt+numpad to enter the keycode. So now he is simply unable to log on to his brand new computer, and there was no windows 8 disk accompanying it so he would be able to reset/reinstall.

Is there anything he can do? Or does he have to take it back to the retailer?

Thanks in advance.

PS: This is obviously a bug -- where does one file bugs for Windows 8?

Try holding Alt and then type 127 in via the Numpad on your keyboard. Let go of the Alt key and it should insert ASCII character 127. Repeat twice more to get three of them.

Note: ASCII 127 is the "Delete" code. So often it will do what it's supposed to and delete a character instead of displaying the 'box' (because it's an unprintable ASCII Code with no actual symbol). So you may just be out-of-luck.
