Is it correct that with Hyper-Threading the processor itself can decide to switch threads?

ie when one thread is "stalled" waiting for something, it can switch execution to another thread

On Multi-Core (Core 2 Duo/Quad) does the OS control thread/task switching?

In either case, it depends on a multi-processing OS. In fact, HT is more dependent on the OS to minimize the resources consumed by a spin-locked thread. For example, HT was the downfall of Windows 2000.
