A CPU will only use an additional core when it needs to. A CPU intelligently manages tasks between its cores and users never know what’s going on. The more cores a CPU has, the more tasks it can handle at once. Specifically, modern CPUs have multiple cores, and they’re able to create and run multiple virtual cores.Ī core allows multiple processes to run. This is made possible by the considerable advancement that’s been made in CPU technology. Note: If you number of processors is incorrectly displayed or disabled, try ticking detect HAL in the BOOT Advanced Options in msconfig and then rebooting first.A modern-day CPU is capable of handling multiple tasks at once. Pick from the list how many cores you want to run.

Run the program as Administrator.Ĭlick the Boot tab and choose Advanced Options.Ĭheck the box labeled Number of processors.

Problems arise when the OS disables a core in error or has difficulty enabling the core again. Often this is to save in power consumption or to assist older programs in working correctly. In some circumstances Windows 7 will disable certain cores. If you have experienced a drastic slowdown in system performance, this could be your quick fix. Problems arise when the Windows OS then never re-enables all the cores. However, in some circumstances windows will set your active cores lower than the max. By default, Windows will run all your cores. However, even if you have a dual, quad, six-core processor, you are not guaranteed that all of them are always turned on. Many games and other processor-heavy applications really require the CPU power of multiple cores.
