Each computer contains at least one processor, also known as a CPU or central processing unit. Your computer's CPU is probably made by Intel or AMD. This is how you see which CPU you have and how fast it is.
You do not need a system information tool to find this information. Windows shows it in several places.
To find this information in the Windows 10 Settings app, navigate to Settings> System> About. See "Device Specifications." The name of the computer's processor and its speed are shown to the right of "Processor".
You can press Windows + I to quickly open Settings. You can also press the Windows key, type "About" to search the Start menu for this setup screen and click the "About this computer" shortcut that appears.
Task Manager for Windows 10 also displays detailed CPU information. Right-click on the taskbar and select "Task Manager" or press Ctrl + Shift + Esc to start it. Click the Performance tab and select "CPU." The name and speed of the computer's CPU is shown here. (If you don't see the Performance tab, click "More Details.")
You will also see CPU usage data and other real-time details, including the number of cores that your computer's CPU has.
Windows 7 or Windows 10 users can find this information in the control panel. Specifically, it is on the system box. Go to Control Panel> System and Security> System to open it. You can also press Windows + Pause on your keyboard to instantly open this window.
The computer's CPU model and speed are shown to the right of "Processor" under the System heading.
If Windows does not start on your system, you can still find this information in several other ways. The computer's documentation probably contains information about system specifications like here. You can also find this information displayed on your computer's BIOS or UEFI firmware setup screen.
