You make a very good point. I would like to show you a comparison of HT
when it first came out to HT more recently. More recent programs have
been better compiled and more and more are supporting HT. See the
differences between these two:
Old - http://www.2cpu.com/articles/43_1.html
New - http://www.2cpu.com/articles/42_1.html

As for the fix, try installing Service Pack 2. When this is finished and
has rebooted, turn off the computer. Turn on the computer, then enter
the BIOS, enable HyperThreading, then let Windows load. It should have
no problems after this point.
