The reason why Windows NT could no compete Linux on servers is

 You don’t think the design of Windows NT contributed to that failure?

No. The design of Windows HAL was great. It is rather the business model Microsoft pursued.

On the other hand you still cannot have decent gaming under Linux.

 Actually, you can. Look at the Steam Deck, which runs a purpose-built GUI
for handheld gaming.

Well, handheld gaming to gaming is like masturbation to love. Sorry...
  Microsoft has been talking about bringing out a

Windows “Handheld Mode” for about two years now, but still has nothing to
ship.

You can. See overlapped I/O.

 I said “poll/select calls”. Do you not know what those are? On Windows,
they work with sockets, but not with pipes. Or even ordinary files. So
unlike *nix systems, you have to keep in mind the different kinds of files
you might be working with.

Again. It is called overlapped I/O. You can start multiple *asynchronous* I/O operations from a thread. It can be done on any sets of file handles. When an I/O event happens on a handle the corresponding event gets signaled. select() behavior is achieved by WaitForMultipleObjects that waits for multiple events. Then you check the overlapped results. If you never wait and only check the overlapped results that would be polling.

And single drive letters?

They are dozens characters long actually, if you mean the device names.

 Drive names are only single letters. You’re not talking about reserved
file names, are you?

No, I am talking about proper file paths under Windows. Letters is a DOS layer on top of it. E.g. see QueryDosDeviceW call.
