How to disable a CPU core

You might want to switch to a processor that has more cores, and see if your fetish softwares are optimized for multi-core. To do this, you can do a simple test by turning off some cores of your current CPU and see what happens.

Tap the Windows + R keys, then enter MSCONFIG > OK > Boot tab > advanced options > Number of processor, enter the required number.

This is the number of logical cores (threads). In general, a processor has twice logical cores comparing to physical cores.

Restart. Do your tests, write down the results. Then change the “number of processors” again.

To reset the number of cores, it will suffice to uncheck the box.
