> This is also why they do Windows on Linux emulation.

They don't. They use WINE, which as the name says, Is Not an Emulator. :D

(I'll let my pedantic self out now)

despite the funny backronym, Wine actually IS a WINdows Emulator. Someone apparently told them that it's only called an emulator if it's emulating a CPU architecture, but that's not true.

I thought it was an implementation of the Win32 API as a compatibility layer.

What is it emulating exactly?

Does Windows NT have a Windows 9x API emulator?

Windows NT predates Windows 95 for two years.

And yes it did had an emulator for Windows 16,
