No, 64 bit was widely adopted long before windows cut support. Keep in mind a 32 bit OS can only use ~4GB of ram, and most systems have been shipping with more than that for many years now.

Towards the end of 32 bit’s life, physical address extension allowed operating systems to use more memory, often up to 40 bits worth, but still could still expose a 32 bit address space to user applications.

Yes, but that would only get the total up to about 5GB, which isn’t very much more.
