I'd bet good money that there are hundreds if not thousands of other buggy installers lurking on windows update, just waiting for the right hardware id to appear. Yes, this is a bit of a shortcut, but not really any different than booting from a USB drive and changing the admin password. Adding Bitlocker to the mix is where it starts to get interesting.

Love Razer mice, but never install their software. And, yes, the way their installer starts via Windows Update should be prevented by Windows.

I can't imagine blaming this one on Razer. It's a fundamental defect in Windows.
