From Microsoft – Windows 10 supports a maximum of two physical CPUs, but the number of logical processors or cores varies based on the processor architecture. A maximum of 32 cores is supported in 32-bit versions of Windows 8, whereas up to 256 cores are supported in the 64-bit versions.

Should I enable all cores in Windows 10?

If you’re using Windows 10, all of your processor cores will be fully utilized by default if your BIOS/UEFI is set correctly. The only time you would use this technique is to limit cores, whether for software compatibility reasons or otherwise.

What programs actually use multiple cores?

The following are examples of CPU-hungry applications that can take advantage of multiple cores:

• Photo and video editing apps— Adobe Photoshop, Adobe Premier, iMovie.
• 3D modeling and rendering programs — AutoCAD, Solidworks.
• Graphics-intensive games — Overwatch, Star Wars Battlefront.
