Windows Vista Hyperthreading Support

swizzy

When i had XP, if i did systeminfo, it showed me two installed processors... however in vista it shows only one, does anybody know the reason, or how to solve it?

Processor: Intel Pentium 4 2.8 GHz Hyper-Threaded
BIOS: Hyperthreading Supported
OS: Windows Vista Ultimate

When i used the hyper-thread test utility from intel, it showed all ok in xp, however it does not work on vista!

Maybe the utility doesn't support Vista yet. Or maybe, just maybe, there's that tiny little tweak that Vista needs so that it recognizes that hyperthreading is enabled. Or maybe Vista is just being sucky that since it can see two but identical CPUs, it just reports one.
