IN CERTAIN WinCases Intel is recommending disabling hyperthreading although HT is one of its top unique selling points.
All operating systems apart from Windows XP, according to Intel, should have hyperthreading disabled. Those include Windows 2K, Win NT 4.0, Win ME, Win 98 and Windows SE.

The operating environments are understandable. But the grown up real OSes?

We don't understand this. Isn't Windows XP just a fancy eye candy version of Windows 2000? We think we should be told.

Or are Intel and Microsoft still as much in cahoots with each other as we always suspected they were? What price the corporate stable image driver platform now?

We think we should be told.

The INQ!

I heard that like a year ago. ;)

NO. I don't think so. At least, not anymore after SP2.

Yet another example of incompetent journalists attempting to write a sensationalist article despite not fully understanding the topic they are writing about.

While the headline "Intel recommends disabling hyperthreading" followed by "IN CERTAIN Cases Intel is recommending disabling hyperthreading although HT is one of its top unique selling points.", sounds pretty shocking...

...It's only when you read further, they recommend disabling it only on operating systems which don't support it in the first place. Hardly a shocking revelation - we've known for about 4 years that one of the new features in windows XP would be support for HT CPUs.

Yet another extremely ignorant sentance: "We don't understand this. Isn't Windows XP just a fancy eye candy version of Windows 2000?". Just because the INQ (crappy The Register clone) "don't understand" something, does not immediatly make them an authority to criticise it or make judgments based upon it. Last time I checked none of the INQ crew happened to be experts on x86 proccessor architectures and instruction sets, or the structure of the Hardware Abstraction Layer in various operating systems.

They probably believe that the only changes made to XP are the ones they can see at first glance - the superficial stuff like visual style support and a few new icons... and they have gone as far as to write a whole article on this misguided assumption.
