Does anyone know why intel doesnt officially support HT in win2k?

[Acanthus]

I've been using HT in windows for months now and it was recently brought to my attention by thugsrock that Win2k doesnt officially support Hyper-Threading technology.

This has leads some people to believe that HT doesnt work at all, but that most certainly is not the case.

Shouldn't your title read why doesn't Microsoft support HT in Win 2k?

It could obviously go either way. Its either a hardware or OS problem.

No. It's definitely a software problem. It is not in MS's interest to support older OS. XP is the new version, 2K is the old version. Why spend money adding new features to the older version? It would be an investment that made no return.

Intel can do nothing to add support to 2K.

It is entirely a software issue. If I remember correctly, it had something to do with how Win2k handles idle processors. Something about the OS sending nops instead of wait.

In case it wasn't clear, Intel has nothing do with why Win2k does not support HyperThreading.

The first Xeons were HT and only Window2000 existed at that point.
