Windows 2k already had an io_uring equivalent. That's more of an example of Linux being out of date due to being based off UNIX.

IOCP, which originated in NT 3.1, is not a circular buffer like io_uring, but both are completion-oriented.
Microsoft introduced I/O Rings, more or less a 1:1 copy of io_uring, in Windows 21H1.

Windows 8/2012 R2 did introduce Registered I/O for WinSock which is very similar to I/O Rings and io_uring.

Where? Completion ports are not an io_uring equivalent.
Win11 does have something similar: https://learn.microsoft.com/en-us/windows/win32/api/ioringap...
