Device Manager Has Multiple Processors? Here's What to Do

Device Manager is a powerful inbuilt tool with Windows operating system that enables users to manage hardware devices connected to their computer.

Modern processors have multiple cores and threads; if a processor has 8 cores with 2 threads per core, that means 16 threads. You will see 16 processors in Device Manager, as Windows treats every thread on the processor as a separate small processor.

If you see a list of processors on Device Manager and want to see if these are legit, then this guide can help! We will also mention how to fix the problem if processors are not working properly and have compatibility issues. Let’s get started! 

Why does my Device Manager have multiple processors? 

There could be various reasons for multiple processors showing in Device Manager; some of the common ones are: 

• Multi-core processors – Modern processors come with multiple cores, which are individual processing units within a single physical processor. Hence you see multiple processors.
• Hyperthreading – If your processors use hyperthreading, which enables a single physical processor core to act as two virtual cores, the operating system sees two processors instead of one. 
• Multiple physical processors – If you have a high-end system, it could have multiple physical processors installed. Hence you will see multiple processors in Device Manager.  
• Virtualization – If your computer has virtual machines, you can see multiple processors in Device Manager, and each reflects the virtual processors allocated to each virtual machine.
