Thankfully one of the Very Shiny Things about Windows 7 (which is very shiny in general) is that you can download a US Windows 7 ISO DVD image from Microsoft itself for your appropriate Win7 subvariant, burn it to DVD, then install it over your Strange Language with the same OEM product key, for free except for the next 5 hours you'll spend installing all Windows Updates and drivers. I just about did a victory dance when I figured it out.
