This is talking about the Windows NT Workstation (or Windows 95 etc.) banner on the left of the original start menu. It doesn’t change when you add programs, and I don’t think the edition branding changes between languages (at least the French versions are still Windows NT Workstation / Server, and if the French didn’t force Microsoft to localise the edition names, I doubt any else would manage). So you could just render once on startup / first menu draw then cache the bitmap. Or just prerender the bitmap as a graphical resource and store it on disc…
