The new information being shared here is Win10 (with the latest updates) can now support DS4 natively - wired and wireless.
It is, for a fact, recognised now by Win10 as a
DirectInput compliant device by default -

As I said in the previous (deleted) post, PCSX2 1.6.0 does not require DS4Windows, but other game launchers/clients may still do.
New information is not false information. It's just new(ish) and not widely known as DS4Windows was the de facto before Microsoft provided native support. I've had perfect wireless enjoyment since last year.
Provided the user gets the latest updates for Win10, it is more likely going to be the same for everyone. Just hit Windows Updates.
After pairing it with bluetooth, PCSX2 detects it automatically as DX Wireless Controller and user can calibrate as usual:
(Note: Where it did not succeed was rumble, but I don't care about that feature much.)
This makes it less fiddly and more user-friendly for people who just want to use their DS4 as they no longer need a 3rd-party app to work with the emulator.
Just so more people know.
P.S.
To its merit, the native Micro$oft support is stable. Calling it unstable due to the single lack of rumble support would be objectively unfair.
