No. The old Zunes' firmware is missing too many functions to be able to run Explorer, which is what everyone seems to want.
The old Zunes can already run Windows CE programs. Doom is one. It uses Windows GDI to render. The only two things that are really missing are a cursor and keyboard.
I do not have an old Zune anymore. Someone else can do that.
