Dave reveals much of what I have suspected from years of Windows use. From the first post DOS Windows up to Windows 11.

 

This program is very reliable:

CPU-Z for Windows® x86/x64 is a freeware that gathers information on some of the main devices of your system :

• Processor name and number, codename, process, package, cache levels.
• Mainboard and chipset.
• Memory type, size, timings, and module specifications (SPD).
• Real time measurement of each core's internal frequency, memory frequency.
• CPU-Z is fully supported on Windows® 11.
