Windows 7 Unicode Text Rendering Missing From Certain Areas

I recently reformatted my PC and have noticed that areas which properly supported Unicode beforehand no longer do. For example, although Unicode text shows correctly in the majority of Windows Explorer, when I right click on files to view the properties the text field that shows the file name isn't rendering it correctly. This also propagates into some parts of other applications which previously had Unicode support, such as Winamp. I have a vast collection of East Asian music so this is more than a minor inconvenience for me.

Please find the below screen shots to demonstrate what I am seeing:



For comparison, here is the same file being displayed properly on my Laptop:
