i'm having trouble with the display of japanese characters on Windows 8 Pro (English, 64-bit, updated regularly). They appear as boxes (picture) in windows explorer, windows menus (even in the language settings of control panel), iTunes and nearly everywhere else, besides web browsers. I was using windows 7 until now, and it didn't have any of these problems, and i'm using the same applications now, as i was using in windows 7. Sometimes (!) when i restart the machine the problem goes away, but that isn't a real solution.

What i've tried so far:

• added japanese language to windows of course

• installed/uninstalled/reinstalled japanase language pack (didn't have any impact though)

• i've read in one of these superuser topics a possible solution, when i had to create a txt file on the desktop with a kanji in the filename - that also didn't work (but i honestly hope that hacking and tweaking an operation system released in 2012 can't be the solution to display kanjis..)

Please give me any ideas, i'm a bit hopeless here, and don't want to spend my life installing operation systems..
