By default, the Windows 8 Task Manager displays only the summary of the processors of the computer. A few clicks are enough to find a more complete display and thus see if the programs are using the hyper-threading of the CPU. An Intel Core i3 dualcore has 4 logical processors while the i5 and i7 quadcore go up to 8 logical processors. CPUs have been multi-core for about ten years with the release of the Pentium 4 HT, a revolution at the time.
1. Open Task Manager (from the desktop, right click on the taskbar).
2. Make a right click on the Processor graph, Change the graph to, Logical processors.
3. The window is now split into as many logical processors as possible. This value depends on the type of processor (socket, cores, logical processors).
We thus find a display closer to what we saw on Windows XP, Vista, 7, Server 2003 and 2008.
