I am aware of what the bulletin says about the hotfix and HT however there has been some controversy over the use of the hotfix with Intel HT. One of the reasons why M$ has not placed that hotfix on Windows update or made it widely known is because it may have an adverse affect on Intel HT and at the time of its release, AMD had not produced an optimizer that would make full use of the hotfix.
Using the hotfix with HT can have both positive and negative affects on systems that make use of logical thread technology. It may make some programs run better and seriously hinder other software. In the conversations I have had around the hotfix and HT, the consensus was it was better to disable HT in the BIOS during use of software which displays negative results with HT enabled than it was to inundate the system with a patch that may not provide the best solution.
HT is not SMP and Microsoft is aware that the hotfix is better suited for SMP use. It does come down to what works best and the only way to know which is better for a system would be to run HT disabled without the patch and then try it with and see what happens.
Many found that simply entering the BIOS and disabling HT prior to MSFS use resolved the performance issues and allowed the user to switch back when finished. At that point the system was free to use software in which HT is of great benefit and may be affected by the hotfix.
