Windows XP Half-Japanese Edition, Service Pack 2 (more commonly known as “Windows XP 半Japanese エディション, Service パック 2″)
Windows isn’t Windows if it doesn’t behave crazy from time to time.
OK, so I installed Japanese fonts (for an obvious purpose). I also installed Japanese IME so that I could input Japanese in a sane way. Last, I set “Language for non-Unicode programs” to Japanese so that I could activate IME on console programs (”Regional and Language Options” -> “Advanced”).
See, I did all those Japanese-related tweaking, but never did I order Windows to set its user interface to Japanese (and I couldn’t see any way to do it). But this is what I get:

I don’t know what caused it. When started, the program was fully in English. When the menu went crazy, other programs were also still fully English.
Oh, and previously I’ve observed half of my Notepad’s menu turning into Japanese. A precious moment, but I delayed taking a screenshot until the computer went down (electricity outage or Windows crash).
Or perhaps Windows has an advanced detection technology that could detect my kanji level. I’ve learned all kanji in the above screenshot. Maybe as I improve, more menu items will turn into Japanese.
