Does anyone know the family of typeface the old Microsoft logo belongs to?

Maybe? #justhelp

Microsoft and 95 are not Arial Black, looks like a thinner version of Arial. I don't think it's true Helvetica because Microsoft didn't have the rights to it I think, I might be wrong. So Arial is substitute for it, just like Times New Roman is for original Times font.

MS Sans Serif

ARE YOU SERIOUS GUYS? ITS FRANKLIN GOTHIC, IT COMES FROM OFFICE TOO

All of the text is Franklin Gothic, just different types.

Windows text is Franklin Gothic ATF Wide

It's FG

franklin gothic heavy italic looks similar to the WINDOWS text

Zurich std black is the one that’s probably used on the WINDOWS text
