Is there "InterlockedRead()"? I suppose no, but I would get confirmation that
a simple memory mov instruction is atomic WRT Interlocked* functions.

If I were writing Interlocked API, I would certainly add InterlockedRead()
and InterlockedWrite() functions, but somehow Microsoft decided that these
functions are redundant.

InterlockedWrite is spelt InterlockedExchange.

Finally, there is a paranoiac implementation of InterlockedRead(&foo):

  result = InterlockedAdd(&foo, 0)

but, IMHO, it is pathetic...

Agreed. Another pathetic implementation:
  result = InterlockedCompareExchange(&foo, 0, 0);
